Tertiary tetraols of adamantane (C10H16, Tricyclo[3.3.1.1(3,7)]decan) have been widely used for the synthesis of highly symmetric compounds with unique physical and chemical properties. The methods for one-stage simultaneously selective, deep, and cheap oxidation of adamantane to tetraols of different structures have not yet been developed. In this research, chemically simple, cheap, and environmentally friendly reagents are used and that is the first step in this direction. The conditions, under which the impact of a hydrogen peroxide water solution on adamantane dissolved in acetonitrile results in full conversion of adamantane and formation of a total 72% mixture of its tri-, tetra-, and penta-oxygenated products, predominantly poliols, have been found. Conversion and adamantane oxidation depth are shown to depend on the ratio of components of the water-acetonitrile solution and the method of oxidizer solution introduction when using the dimer form of 1:1 dimethylglyoxime and copper dichloride complex as a catalyst. Under the conditions of mass-spectrometry ionization by electrons (70 eV), fragmentation across three C–C bonds of the molecular ions framework of adamantane tertiary alcohols Ad(OH)n in the range n = 0–4 increases linearly with the rise of n.

Dehydrogenation processes play an important role in the petrochemical industry. High selectivity towards olefins is usually hindered by numerous side reactions in a conventional cracking/pyrolysis technology. Herein, we show recent studies devoted to selective ethylene production via oxidative and non-oxidative reactions. This review summarizes the progress that has been achieved with ethane conversion in terms of the process effectivity. Briefly, steam cracking, catalytic dehydrogenation, oxidative dehydrogenation (with CO2/O2), membrane technology, and chemical looping are reviewed.

In this study, an approach for the preparation of heterogeneous acid catalysts based on asphaltenes isolated from vacuum residue is proposed. Varying the conditions for the sulfonation of asphaltenes made it possible to obtain materials with an acid value of 1.16 to 2.76 meq g−1 and a total sulfur content of 6.4 to 12.3 wt%. The samples obtained were characterized by acid-base titration, nitrogen adsorption, sulfur elemental analysis and transmission electron microscopy techniques, and were studied as potential acid catalysts in the ketalization reaction between glycerol and acetone. Sulfonated asphaltenes (SA) were characterized by a homogeneous distribution of sulfonic groups over the granule surface and an almost complete absence of a porous structure. The ketalization reaction in the presence of SA proceeded without intradiffusion restrictions; as a result of which, their activity was higher than for known heterogeneous catalysts. The most active SA sample (total acid value, 1.16 meq g−1) had an apparent activation energy of 18.0 kJ mol−1, which was lower than the value obtained for the zeolite BEA-40 (29–53 kJ mol−1) and the Amberlyst 36 resin (27 kJ mol−1), and was close to the value for the homogeneous p-TSA catalyst (14.5 kJ mol−1). The SA heterogeneous catalysts did not show any acid leaching and had no loss of activity after five catalytic cycles, with the total turnover number TON = 7247.

Non-phosphorous rhodium-containing catalysts for direct conversion of olefins to alcohols via tandem hydroformylation/hydrogenation have been designed and synthesized. Interaction between Rh(acac)(CO)2 and tertiary amino groups on the surface of mesoporous hybrid organic-inorganic supports yielded materials which were successfully used in the tandem process. Data obtained for a selected catalyst KN demonstrate that rhodium is in the Rh+1 state highly dispersed on the surface and is bonded with nitrogen atoms both before and after use. Evaluation of the catalytic performance shows high activity (hydroformylation TOF 312 h−1), chemoselectivity and stable hydroformylation yield at least in the first 5 cycles with a decrease in alcohol selectivity. The influence of temperature, reaction time, total pressure, and molar CO/H2 ratio of syngas on oxygenate yields is described. Type of the hydroformylation active sites and possible pathways for the observed decrease in hydrogenation are discussed.

Methods for preparing zeolites with the particle size of 50–200 nm using mechanical milling on bead mills (top-down approach) are analyzed. The milling can be described by a first-order rate equation, but mathematical models allowing prediction of the particle size and degree of crystallinity of zeolite after milling, based on the process parameters, are still lacking. The milling is accompanied by degradation of the zeolite lattice, leading to a decrease in the zeolite crystallinity and activity in catalytic reactions. Recrystallization and dealumination may be promising ways to restore the zeolite structure after milling; in this case, the choice of the conditions for such posttreatment is of crucial importance. Evolution of textural and acid properties of zeolites in the course of milling is considered, and the effect of milling conditions on the catalytic activity of zeolites in various reactions is discussed. The main outcome from a decrease in the size of zeolite catalysts is an increase in their activity and a decrease in the deactivation rate.

In this work, the composition, structural and morphological features, and particle size of the active phase of the catalyst (MoS2), synthesized in-situ during the heavy oil hydroconversion performed in continuous flow reactor on lab-scale pilot flow unit at T = 450 °C, P = 6.0–9.0 MPa, V = 1.0 h−1, H2/feed = 1000 nL/L, catalyst concentration C (Mo) = 0.01–0.08%wt have been studied. It has been shown that MoS2 formed during hydroconversion is represented by nanosized particles stabilized by polycondensation products as a result of strong adsorption and aggregation with the components of the hydroconversion reaction medium. The influence of morphological characteristics of catalyst nanoparticles on the feed conversion, the yield of gaseous and liquid products, and the quality of distillate fractions, as well as the yield of polycondensation products, have been studied. It has been established that an increase in MoS2 active site dispersion, both due to a decreased plate length and lower stacking numbers in MoS2 cluster, enhances hydroconversion effectivity, particularly, in suppressing polycondensation reactions.

The present work is dedicated to the nickel phosphide based catalysts, containing particles, generated in situ in the reaction medium from the different catalytic systems. The present catalytic systems exhibited high activity in the hydroprocessing of furfural. Full conversion of furfural depending on conditions was reached after 0.5−3 hours of reaction at 250−350 °C. 2-methylfuran was obtained as a main product in toluene with the highest selectivity of 77 %. Ethyl levulinate and 2-methylfuran with selectivity of 40 % and 38 % respectively were obtained as main products in ethanol under different conditions. Different reaction medium and nickel phosphide precursors had an influence on the obtained phases of catalysts. Ni12P5 and Ni2P were obtained in toluene from oil-soluble precursors and Ni12P5 was obtained in ethanol from water-soluble precursors.

In this paper, we developed an effective method for purifying oil sludge using a sorbing electrochemical matrix and assessed the prospects of this method in comparison with conventional hydrocracking. We synthesized Ni-W supported hydrocracking catalysts with different morphology and studied their activity under various conditions, we compared the obtained catalysts with commercial catalyst SGK-5. We demonstrated that the introduction of a secondary mesoporous structure in the catalyst leads to an increase in the yield of light fractions to 52 wt.%. The possibility is demonstrated to obtain hydrocarbons from reservoir oil sludge, dispersed into an aqueous solution of detergent, by the method of low-temperature hydrogenation in sorbing electrochemical matrices. The obtained product was characterized by low viscosity, low content of transition metals (<320 ppm), and sulphur (<260 ppm).

The active use of transition metal phosphides in catalysis commenced at the beginning of the 2000s primarily in hydrodesulfurization and hydrodenitrogenation reactions. Owing to an increased interest in biomass-based feedstocks the intensive use of phosphides in hydrodeoxygenation reactions started in the first part of the 2010s. In earlier reviews devoted to phosphides, which were published before the 2010s, no information pertaining to hydrodeoxygenation is available. This review addresses monometallic phosphides of such transition metals as nickel, cobalt, molybdenum, and tungsten and covers their structure, synthesis, and properties. Transition metal phosphides are promising catalysts for hydroprocesses. They possess both metal active sites and acid sites, and, therefore, demonstrate activity not only in hydrogenation but in a number of acid-catalyzed processes. The review concerns the hydrodeoxygenation reactions of higher fatty acids and their esters; vegetable oils; and bio-oil and its model compounds. The hydrotreatment of vegetable oils and their derivatives over phosphides makes it possible to obtain hydrocarbons, which can be used as diesel fuel components or as a pure fuel. Using the hydrodeoxygenation of bio-oil model compounds catalyzed by phosphides partially or fully deoxygenated products may be obtained; however, the hydrotreatment of bio-oil itself did not provided positive results so far and calls for further research.

Copper-containing catalytic slurries with different concentrations of active metal precursor solutions are synthesized by drop thermolysis in situ in the hydrocarbon medium of a slurry reactor. According to dynamic light scattering, the particle size of the catalytic slurry dispersion phase is 3–4.5 nm and it remains almost unchanged during the synthesis. Using FTIR spectroscopy it is shown that the structure of precursors of slurry active species depends on the concentration of solution, which may influence the phase composition of catalytically active fragments of the surface during the reduction and synthesis of alcohols. It is demonstrated that alcohols may be synthesized from CO and H2 in the slurry reactor in the presence of the formed nanosized slurries. It is revealed that the composition of alcohol phase products differs significantly with target product selectivity being comparable: at a low concentration of precursor solution a marked amount of methanol is contained in the mixture (up to 66%), while an increase in the concentration of precursor solution causes a rise in the proportion of higher molecular weight alcohols to 88%.

The hydrocracking reaction of a pyrolysis fuel oil fraction using in situ generated nano-sized NiWS-sulfide catalysts is studied. The obtained catalysts were defined using X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). The features of catalytically active phase generation, as well as its structure and morphology were considered. The catalytic reactivity of in situ generated catalysts was evaluated using the hydrocracking reaction of pyrolysis fuel oil to obtain a light fraction to be used as a feedstock for benzene, toluene, and xylene (BTX) production. It was demonstrated that the temperature of 380 °С, pressure of 5 MPa, and catalyst-to-feedstock ratio of 4% provide for a target fraction (IPB −180 °С) yield of 44 wt %, and the BTX yield of reaching 15 wt %.

Features of the mechanism of dimethyl ether (DME) conversion to olefins over ZSM-5 zeolite catalysts were studied using experimental and theoretical methods of vibrational spectroscopy. A catalytic activity comparison of the catalysts Mg-HZSM-5 without a binder and Mg-HZSM-5/Al2O3 containing 1% Mg (by weight) and 33% Al2O3 (by weight) as a binder in the DME conversion was carried out. Using high-temperature diffuse reflectance IR (DRIR) spectroscopy in situ combined with quantum-chemical simulations in the temperature range of 25–450 °C in a stream of dry Ar and DME, the bands corresponding to OH bonds, including BAS and H3O+, were interpreted. Depending on the temperature and the presence of magnesium and a binder in the catalyst composition, the intensity and position of these bands maxima vary greatly. The intermediates of the catalytic DME conversion were discovered and identified. At low temperatures (below 200 °C), in a DME stream, methoxy groups (CH3O-Al-), ketene (CH2 =C=O), and a carbocation (CH3 +) were formed on the surface of the catalysts. As the temperature rises (above 300° C), the bands from ketene completely disappear in the spectra of catalysts, and bands from oxonium cations or ylide particles appear, leading the process of DME conversion by the oxonium-ylide mechanism. In the presence of H3O+, the conversion of DME on the zeolite catalyst surface was more effective; however, selectivity for olefins was lower.

Molybdenum and tungsten catalysts, PAF-30-Mo and PAF-30-W, synthesized based on a porous aromatic framework PAF-30 have been tested in the epoxidation of cyclohexene with tert-butyl hydroperoxide. The influence of the temperature and the substrate to oxidant ratio on the characteristic features of the process has been studied. It has been shown that the catalysts exhibit high activity and make it possible to obtain cyclohexene epoxide in a high yield; however, they lose their activity over time due to the leaching of the metal from the pores of the polymer.

The current work describes an attempt to synthesize hybrid materials combining porous aromatic frameworks (PAFs) and dendrimers and use them to obtain novel highly active and selective palladium catalysts. PAFs are carbon porous materials with rigid aromatic structure and high stability, and the dendrimers are macromolecules which can effectively stabilize metal nanoparticles and tune their activity in catalytic reactions. Two porous aromatic frameworks, PAF-20 and PAF-30, are modified step-by-step with diethanolamine and hydroxyl groups at the ends of which are replaced by new diethanolamine molecules. Then, palladium nanoparticles are applied to the synthesized materials. Properties of the obtained materials and catalysts are investigated using X-ray photoelectron spectroscopy, transmission electron microscopy, solid state nuclear magnetic resonance spectroscopy, low temperature N2 adsorption and elemental analysis. The resulting catalysts are successfully applied as an efficient and recyclable catalyst for selective hydrogenation of alkynes to alkenes at very high (up to 90,000) substrate/Pd ratios.

A norbornane derivative, exo-tetrahydrodicyclopentadiene, is the main component of the high-density liquid fuel called JP-10. In the current communication we describe the preparation of some related norbornane-containing hydrocarbons and their energetic properties. The desired hydrocarbons were readily obtained in high yields using Diels-Alder and/or cyclopropanation reactions from the industrially available 5-vinyl-2-norbornene. As a result, the hydrocarbons containing two norbornane moieties or norbornyl and cyclopropyl groups were prepared. The heats of combustion, densities and freezing points of the prepared norbornane derivatives were evaluated. High densities in the range of 0.856–0.977 g/cm3 and low freezing points (below −60 °C) were found for the obtained hydrocarbons. By altering the structure of such a hydrocarbons, the energy density as high as 41.24 MJ/L was achieved. The energy densities for the hydrocarbons consisting of two norbornane moieties or norbornyl and cyclopropyl fragments were noticeably higher than that of JP-10. Taking into account the low freezing points, high densities and high energy densities, the developed norbornane-type hydrocarbons can be considered as a promising components for high-energy density liquid propellants.

The main physico-chemical features, as well as gasoline blending features of eight diol derivatives (1,3-diisopropyl and 1,3-di-tert-butyl glycerol ethers – di-GIPE and di-GTBE; O-isopropyl and O-tert-butyl solketal ethers – SIPE and STBE; isopropylidene ketals of ethylene and propylene glycol – DMD and TMD; cyclic ketals of glycerol with the methyl ethyl ketone and the methyl isobutyl ketone – GBK and GHK) have been estimated in order to reveal the relations between the molecular structures of the compounds and their efficiency as the gasoline oxygenated additives. For the oxygenates, the experimental values of the density, the boiling/melting point, the viscosity and the net heat of the combustion have been obtained. The characteristics of the estimated oxygenate-gasoline blends have involved their density, the calorific value, the fractional composition, the saturated vapor pressure, the research octane number and the motor octane numbers (ON), the oxidation stability, the gum content and the pour point. For di-GTBEs, as the most effective octane booster (among the compounds tested), the effect on the gasoline calorific value has been researched in the combination with the antiknock features improvement, which shows the evident advantages over ethanol and MTBE relatively to ΔAKI/ΔNHOC ratio.

Hexadecane hydrocracking was investigated over bifunctional Ru-containing micro- and mesoporous USY zeolites at 250°C under 45 bar in the presence of hydrogen in a batch reactor. A comparative study was performed using the Ru-free zeolites in the protonic form. The highest yield of jet-fuel products, C9 - C15, being 26% at 71% conversion, was obtained with 2.5 wt% Ru deposited on a hierarchical micro-mesoporous USY zeolite, e.g. a material possessing secondary porosity, where a superior combination of acidity and mesoporosity was created by treatment of the parent zeolite with aqueous sodium hydroxide and tetrapropylammonium hydroxide.

In this study, two oil fractions – straight-run diesel and light cycle oil (LCO) – and the products of their hydrotreatment with sulfide catalysts, synthesized in the pores of porous aromatic frameworks, were analyzed by comprehensive two-dimensional gas chromatography (GC) with time of flight mass spectrometry (GC × GC–TOFMS). Effective separation of numerous compounds in the analyzed multicomponent mixtures and high resolution of mass spectra of reaction products made it possible to study the features of the activity of sulfide catalysts.
