The article presents an analysis of the intellectual property market in the field of enhanced oil recovery (EOR) methods. The search retrospectively covers the period from 2010 to 2020. Russia, China, and the United States are the leading countries in enhanced oil recovery methods. Canada, Germany, and Saudi Arabia also have a high level of patent activity compared with other countries. Semantic and statistical analysis of the obtained sample of documents made it possible to highlight the areas of intensive patenting, high competitiveness, as well as mainstream methods of enhanced oil recovery. The analysis of the leading companies’ patent portfolios revealed the similarities and differences in their structure. Tatneft, ConocoPhillips Co., Sinopec, and PetroChina Co. are actively patenting in the field of thermal enhanced oil recovery, which has been identified as the mainstream. BASF SE is focused on the production of chemicals, including chemicals for oil production. The Saudi Arabian Oil Company produces light oil using waterflooding and physicochemical methods. Software dominates the patent collection sector in the EORs of Gazpromneft STC and Lukoil.

The demand for alternative sources of clean, sustainable, and renewable energy has been a focus of research around the world for the past few decades. Microbial/enzymatic biofuel cells are one of the popular technologies for generating electricity from organic substrates. Currently, one of the promising fuel options is based on glucose due to its multiple advantages: high energy intensity, environmental friendliness, low cost, etc. The effectiveness of biofuel cells is largely determined by the activity of biocatalytic systems applied to accelerate electrode reactions. For this work with aerobic granular sludge as a basis, a nitrogen-fixing community of microorganisms has been selected. The microorganisms were immobilized on a carbon material (graphite foam, carbon nanotubes). The bioanode was developed from a selected biological material. A membraneless biofuel cell glucose/oxygen, with abiotic metal catalysts and biocatalysts based on a microorganism community and enzymes, has been developed. Using methods of laboratory electrochemical studies and mathematical modeling, the physicochemical phenomena and processes occurring in the cell has been studied. The mathematical model includes equations for the kinetics of electrochemical reactions and the growth of microbiological population, the material balance of the components, and charge balance. The results of calculations of the distribution of component concentrations over the thickness of the active layer and over time are presented. The data obtained from the model calculations correspond to the experimental ones. Optimization for fuel concentration has been carried out.

Microbial fuel cell (MFC) is a new technology that uses microorganisms to extract energy from complex organic mixtures. On the basis of aerobic granular sludge we have selected a nitrogen-fixing community of microorganisms that was immobilized on a carbon material (graphite foam, carbon nanotubes). The MFC anode has been developed on the basis of selected biological material. A membraneless glucose / oxygen MFC with bioanode and cathode based on non-platinum group metals or laccase enzyme has been developed. A mathematical model describing the processes in the MFC has been developed, on its base the calculations have been carried out.

The activity of a bioeletrode is largely determined by the amount of enzyme adsorbed on its active layer, including the distribution of enzyme along thickness in the carrier layer. The distribution of enzyme is also required for calculations of the characteristics of bioelectrocatalysis process using a mathematical model. In the present article, on the basis of conducted experimental research a mathematical model of laccase immobilization by spontaneous adsorption on carbon-based sorbentsof different nature was developed. The model can be used to predict adsorption value and enzyme distribution in the layer of an adsorbent. The model includes the equations of the enzyme concentration changing due to its adsorption on the surface of the carbon material (CM) and the enzyme diffusion over the thickness of CM. The diffusion equation is based on the second Fick's law and contains fractional derivatives instead of the first oder derivative.

HiSPEC 13100-monoplatinum-catalyst-based cathode for hydrogen–air (hydrogen–oxygen) fuel cell with proton-conducting polymer membrane is studied. The cathodes of membrane–electrode assemblies with different platinum load were subjected to accelerated stress-tests for the purpose of the revealing of peculiarities of the cathode degrading and its electrochemical parameters’ changing, depending on the platinum load in active layers. The cathodes with lower platinum load were shown to have better characteristics, such as the mass activity and platinum utilization coefficient. However, they are much more prone to degradation and increased transport losses at limiting currents as compared with high-platinum-loaded cathodes. A degradation mechanism is suggested, which basically allows for the platinum nanoparticles coalescence.

This study continues an earlier work devoted to simulation of mass transfer in liquid-liquid systems taking into account mass transfer across fractal interfacial structures. Earlier, using methods of nonequilibrium thermodynamics, we obtained an expression for the generalized thermodynamic force taking into account colloidal chemical phenomena in the interfacial region, such as the formation of disperse interfacial layers and films. Here, using a differential equation with a fractional-order derivative, we estimate the diffusion coefficient of the extractable substance in the interfacial film and the porosity of this film, which is its structural characteristic.

A mass transfer model in which the generalized thermodynamic force accounting for colloidal and chemical phenomena in the interfacial zone, such as the formation of disperse interfacial layers and films, is taken to be the driving force is considered. A method for calculating the difference between the pressures in the film and in the phase, the interfacial-film thicknesses, and mass transfer coefficients is proposed. It is found that the resistance to mass transfer in porous films varies with time, passing through a maximum.
