As the shortage of non-renewable fossil fuels, the renewable fuels should be further developed. Biomass energy has emerged the great utilization potential, and liquefaction of biomass is a typical technology. This paper studied the effect of the operation parameters on the hydrothermal liquefaction of corn straw using a batch reactor, including liquefaction temperature, initial pressure, retention time, solvent, and catalyst. The optimal liquefaction conditions for corn straw were 300 °C under 4 MPa for 15 min using the mixture of water and methanol as the solvent. After the addition of catalyst, NKC-11 catalyst showed the excellent performance, and the primary components were phenol and derivatives, alkane, furan, and the low concentration of organic acids. Lastly, the life cycle assessment on the hydrothermal liquefaction of corn straw for bio-oil production was executed. The results of LCA suggested that a net 1.31 kg of CO2 equivalent was produced for 1 kg of bio-oil product without considering syngas, while the value changed to 13.03 kg with considering syngas. Moreover, the results of sensitivity analysis further suggested that the syngas was a key factor on the environmental impacts in the hydrothermal liquefaction of corn straw process.

Bisphenol S (BPS), regarded as a valid alternative to Bisphenol A (BPA), has been found to induce acute toxicity, genotoxicity. In this paper, BPS pollution was repaired by corn straw biochar, and the effect of dissolved organic matter (DOM) on the remediation mechanism was investigated. Different DOMs were obtained by decomposing corn straw in red soil, yellow soil and brown soil. The DOMs were characterized by Elemental analysis, Fourier infrared spectroscopy (FT-IR), ultraviolet–visible spectroscopy (Uv–vis) spectroscopy, Three-dimensional excitation-emission matrix (3D-EEM). Different kinds of DOMs were added into the biochar adsorption system to determine the optimal pH, optimal dosage, equilibrium adsorption capacity, adsorption kinetics, adsorption isotherms, thermodynamic characteristics, and explore the influence mechanism of DOM on the adsorption of BPS by biochar. The results of the adsorption experiments showed that DOM would suppress the BPS adsorption capacity on biochar. In addition, the DOM, produced by decomposition of corn straw with brown soil, had the strongest inhibitory effect on adsorption, and red soil was the soil with the lowest inhibitory effect on organic pollution removal by biochar.

The liquefaction of biomass is an important technology to converse the biomass into valuable biofuel. The common technologies for liquefaction of biomass are indirect liquefaction and direct liquefaction. The indirect liquefaction refers to the Fischer–Tropsch (F–T) process using the syngas of biomass as the raw material to produce the liquid fuel, including methyl alcohol, ethyl alcohol, and dimethyl ether. The direct liquefaction of biomass refers to the conversion biomass into bio-oil, and the main technologies are hydrolysis fermentation and thermodynamic liquefaction. For thermodynamic liquefaction, it could be divided into fast pyrolysis and hydrothermal liquefaction. In addition, this review provides an overview of the physicochemical properties and common upgrading methods of bio-oil.

It is a promising pathway to reduce the dependence on fossil fuels and obtain the bio-fuels or chemicals production from biomass derivatives. The conversion from furfural (FFR) to furfuryl alcohol (FFA) is an important industrial technology using the liquid-phase hydrogenation method with external hydrogen gas. However, the natural environment is threatened by the security of external hydrogen gas, toxicant catalyst, and the high energy consumption. Recently, in-situ hydrogenation is a novel method to converse FFR to FFA at mild reaction conditions to replace the dangerous external hydrogen gas. In this paper, we reported an efficient in-situ hydrogenation method via aqueous-phase reforming of methanol using Pt loading MgTiO3 (perovskite-type material) at mild conditions. Pt nanoparticles were high dispersion on the nano-MgTiO3-450 surface, and CH3OH and H2O were reformed to produce hydrogen gas on the catalyst surface through the action of Pt nanoparticles. A part of active hydrogen could be involved in the reduction of Pt2+ to Pt0, resulting in the perfect recyclability of the [email protected] catalyst. The other part of active hydrogen were participated in the hydrogenation of FFR conversion to FFA under the interaction of Pt and Mg elements. The in-situ hydrogenation of FFR to FFA using [email protected] is an effectively pathway to reduce the reaction conditions than that with external hydrogen gas.

As a new functional material, biochar was usually prepared from biomass and solid wastes such as agricultural and forestry waste, sludge, livestock, and poultry manure. The wide application of biochar is due to its abilities to remove pollutants, remediate contaminated soil, and reduce greenhouse gas emissions. In this paper, the influence of preparation methods, process parameters, and modification methods on the physicochemical properties of biochar were discussed, as well as the mechanisms of biochar in the remediation of soil pollution. The biochar applications in soil remediation in the past years were summarized, such as the removal of heavy metals and persistent organic pollutants (POPs), and the improvement of soil quality. Finally, the potential risks of biochar application and the future research directions were analyzed.

Bisphenol S (BPs) has been found in a variety of common consumer products surrounding human living, despite the fact that it could damage the human digestive system and genital system. In China, straw-returning to the field is a common soil improvement technology used to increase the concentration of dissolved organic matter (DOM), which plays an important role in the natural environment as a microreactor of contaminants. Additionally, the biochar obtained by the straw is an effective soil conditioner. DOM is a key influencing factor when biochar is employed as the conditioner of BPs contaminated soil. However, the BPs adsorption behavior on the Ferralsol affected by DOM and biochar is also unclear. Hence, DOM was prepared and the effect of DOM on the BPs adsorption behavior on soil and biochar modified soil was investigated. DOM was characterized by Elemental analysis, Fourier transforming infrared spectra (FT-IR), and three-dimensional excitation-emission matrix spectra (3D-EEM). The results of the adsorption experiments indicated that both biochar and DOM could improve the BPs adsorption capacity in Ferralsol, while DOM suppressed the BPs adsorption capacity of biochar modified soil, indicating that DOM and BPs could not be applied at the same time for BPs adsorption.

Biochar is frequently applied for the reduction of mercury (Hg) migration in soil; however, most of the studies only focused on the adsorption capacity evaluation of fresh biochar. We investigated the Hg adsorption capacities of biochar prepared from wheat straw, corn straw, and sunflower seed shells. Biochar aging was simulated via natural aging, high-temperature aging, and freeze-thaw aging. The adsorption capacities of all the aged biochar were increased, and wheat straw biochar and seed shells biochar treated with high-temperature aging (wBC-Ha500 and sBC-Ha600) and corn straw biochar treated with freeze-thaw aging (cBC-Fta500) showed an observable improvement on the equilibrium adsorption amounts. The kinetics of the fresh biochar samples fitted the pseudo-first-order kinetic model and the pseudo-second-order kinetic model, while the kinetics of the aged biochar samples fitted the pseudo-second-order kinetic model. Biochar adsorption capacity increased with higher initial concentrations and increasing temperatures. Elemental analysis, Fourier-transform infrared spectroscopy (FT-IR) spectra, cation-exchange capacity (CEC), surface area (SA), zeta potential, and X-ray photoelectron spectroscopy (XPS) showed that the aging mechanism consisted of hydroxylation and carboxylation caused by the functional groups on the biochar surface. According to the different climatic zones in China, wheat straw biochar and seed shell biochar are suitable for the tropical zone and the subtropical zone, while corn straw biochar is more suitable for the cold and the mid-temperate zones.

Biochar is an excellent absorbent for most heavy metal ions and organic pollutants with high specific surface area, strong aperture structure, high stability, higher cation exchange capacity and rich surface functional groups. To improve the selective adsorption capacity of biochar to designated heavy metal ions, biochar prepared by agricultural waste is modified via Ionic-Imprinted Technique. Fourier transform infrared (FT-IR) spectra analysis and X-ray photoelectron spectroscopy (XPS) analysis of imprinted biochar (IB) indicate that 3-Mercaptopropyltrimethoxysilane is grafted on biochar surface through Si–O–Si bonds. The results of adsorption experiments indicate that the suitable pH range is about 3.0–8.0, the dosage is 2.0 g·L−1, and the adsorption equilibrium is reached within 960 min. In addition, the data match pseudo-second-order kinetic model and Langmuir model well. The computation results of adsorption thermodynamics and stoichiometric displacement theory of adsorption (SDT-A) prove that the adsorption process is spontaneous and endothermic. Finally, IB possesses a higher selectivity adsorption to Cd(II) and a better reuse capacity. The functionalized biochar could solidify designated ions stably.

Corn stalks were modified by magnesium loading and an oxidation process and then characterized by a series of methods. The ammonium in wastewater showed high sorption efficiency onto the polymeric adsorbing material during the process, with a biochars dosage of 20 g/L for 8h. Mg2+ was the dominant cation exchanger on the modified corn stalk, and it played an important role in ammonium sorption. Large amounts of NH4+ were exchanged onto the corn stalk, and they formed strong complexes with oxygen-containing groups on the corn stalk surface through polar bonds, resulting in the removal of NH4+ from the solution. Na+ present in wastewater was the major influence on ammonium sorption onto the corn stalk.

The realization of Ti3+ self-doping and exposure of a hollow structure in TiO2 photocatalysts has been proven to be an effective approach for significantly improving their photocatalytic performance. Herein, a facile and green strategy that consists of microwave-assisted ionic liquid synthesis followed by a vacuum-activation process is developed for synthesizing highly active Ti3+ self-doping TiO2 with a hollow structure. The results of X-ray diffraction, N2 sorption, Raman, X-ray photoelectron spectroscopy, fluorescence spectrophotometry, scanning electron microscopy transmission electron microscopy and scanning transmission electron microscopy analyses revealed that the presence of the ionic liquid [Bmim][BF4] acted not only as a microwave absorbent for the solvothermal process but also as a morphology-controlling agent via a dissolution-recrystallization process, leading to a mesoporous structure. Moreover, the subsequent vacuum calcination process modified the TiO2 to provide highly air-stable Ti3+ and oxygen vacancies. Compared with the benchmark material P25 and other TiO2 nanostructures synthesized using [Bmim]Cl and different molar ratios of [Bmim][BF4], the Ti3+ self-doped TiO2 with a hollow structure was used as an efficient photocatalyst, and it exhibited a 4.6-fold enhancement in photocatalytic activity for the selective oxidation of benzyl alcohol due to its enhanced visible-light absorption, efficient molecular oxygen adsorption ability and improved charge-separation efficiency under visible-light irradiation. Furthermore, the unique disordered core/ordered shell protects the TiO2-x nanoparticle core from further oxidation and effectively blocks oxidation between the Ti3+ and dissolved oxygen in the solvent, thereby allowing long-term recycling stability. The possible reaction mechanism for the photocatalytic selective oxidation of benzyl alcohol over Ti3+ self-doped TiO2 hollow nanocrystals has also been investigated. The results obtained in this study may shed light on improving the photoactivity in fabricating defective TiO2 and defect-based nanostructures and their applications in solar energy conversion.

In this study, alumina-doped MgO was produced as a solid alkali for lignocellulose pretreatment. Pretreatment with alumina-doped MgO disrupted the lignocellulose structure and significantly reduced the lignin content of the Z. japonica. After pretreatment, Z. japonica showed significant solubility in 1-allyl-3-methylimidazolium chloride (AMIMCl). The similar high solubility of pretreated Z. japonica samples by original alumina-doped MgO and used alumina-doped MgO also proved that alumina-doped MgO had strong stability, which can be recycled and used repeatedly. The regenerated cellulose was similar to microcrystalline cellulose according to FTIR and NMR analyses. Compared to microcrystalline cellulose, only the crystallinity of the regenerated cellulose decreased.

We investigated the use of ionic liquid (IL) 1-allyl-3-methylimidazolium chloride (AMIMCl) for extracting cellulose from Zoysia japonica by using Fourier transform infrared spectroscopy, nuclear magnetic resonance, scanning electron microscopy and thermogravimetric analysis to analyze the IL and its effects on cellulose extraction. After water pretreatment at 121 °C for several minutes, cellulose extraction rate was 71% under optimized conditions, and the yield of cellulose was >99% by AMIMCl. The effectiveness of AMIMCl as an extraction agent can be attributed to the prevalence of intra- and inter-molecular hydrogen bonding in cellulose. By contrast, hemicelluloses were not recovered by AMIMCl because hemicelluloses in plant cell walls are connected to lignin by covalent bonding. Results also showed that the regenerated cellulose was exactly the same as untreated cellulose, except for the degree of crystallinity.

In China, more than 1billion tons biomass solid waste containing lignocellulose (such as stalks, straws and landscaping waste etc) is produced. This essay analyzes advantages and disadvantages about landfill, gasification, incineration and biodegradation. Although they have been studied for several decades, there are no efficient treatment processes in use. Only biodegradation will be the environmentally friendly technology. Combining with the technological development, managements and policies also play a great importance role in environmental protection. The government enacts laws and policies etc and supervises to ensure effective implementation by using certain measures. To a certain extent, environmental protection will hinder the rapid economic growth. But good environmental conditions will lead to high-yield low-pollution industries which are more profitable. In this essay, tax and subsidy policies, environmental awareness, green consumption and international cooperation etc are mentioned. So if we can balance relationship between biomass solid waste resources technology, managements, policies and economic development, China will realize leapfrog development in the near future
