The widespread adoption of biomass as an energy fuel is hindered by a number of its significant drawbacks, such as low heating value, low ash melting point, low bulk density etc. Technological solutions that allow to fully overcome these shortcomings and ensure high economic performance have not yet been proposed, although there is a significant demand for them. A new technology for thermal processing of biomass into gas fuel, based on the pyrolysis process, has been developed at the Joint Institute for High Temperatures of the Russian Academy of Sciences (JIHT RAS). The degree of energy conversion of the processed raw materials in the proposed technology is about 75%. The gas fuel yield is ∼1.3 m3/kg of biomass, and its heating value, on average, is 11 MJ/m3. The content of the liquid phase in the energy gas obtained by the developed technology is not more than 50 mg/m3. The gas produced by the technology under consideration on average consists of 90% hydrogen and carbon monoxide. According to existing standards, this gas can be used as a fuel for mini-CHP with gas-piston engines. A promising direction for using this gas is the production of liquid motor fuels.

The article describes the catalytic cracking of heavy oil residue in the presence of a finely dispersed catalyst. It was determined that in the processing of high molecular weight hydrocarbons, catalysts are effective, which are uniformly distributed in the volume of raw materials and are introduced into the technological process in the form of small particles. Coke tar mainly consists of 27.00 wt.% asphaltenes, 60.00 wt.% of polyaromatic hydrocarbons that have been studied and identified as a potential source of raw materials to produce motor fuels in the future.

In recent years, an increased interest has been shown in fuels derived from renewable energy resources of animal and vegetable origin, raw materials of which are practically unlimited. The use of biofuels makes it possible not only to replace petroleum motor fuels with alternative ones, but also to improve exhaust gas toxicity indicators (as a rule, there is a marked decrease in emissions of toxic exhaust gas components). This work is devoted to the study of the possibilities of solving these problems in order to adapt diesel to biogas, a theoretical study of ways to create an experimental model of a power plant for generating electricity from biogas, a theoretical study on the processes occurring in the main components of the plant being developed and the creation of this plant.

The results of studies on the development of a new process of thermal cracking of tar oil as a slurry with crushed oil shale to obtain components of motor fuels. The results suggest doubtless advantages of the process before the industrial of thermo cracking, since the single-stage processing of raw materials in relatively in the mild conditions (5 MPa, 425 °C, volumetric feed rate 1.0 h-1) is achieved deep destruction of tar oil (the yield petrol fraction with a bp amounts to up to 180 °C – ~12 mass % of middle distillates with a bp 180-360 °C – 43-44 mass %, of raw material for catalytic cracking of a bp 360-520 °C – ~15-16 %, based on the initial tar oil). Formed like coke products and raw materials contained in V and Ni is postponed on the mineral part of slate and removed from the reaction zone with the liquid products of the process.

At present, the disposal of polymer and rubber waste, and especially automobile tires, is one of the most acute environmental problems. These types of waste pollute the environment both when they are stored at landfills and during subsequent disposal, especially if it is carried out in the form of incineration. Therefore, at present, much attention is paid to thermal methods of their processing. The results of the study of liquid product of pyrolysis of tires of Kuznetskecology+ LLC are presented in the work. During its distillation, the following fractures were obtained (the yield wt% is indicated in parentheses): petroleum (4), gasoline (21), kerosene (18), diesel (47), fuel oil (10), for which the refractive index was determined and a conclusion about their chemical composition was drawn. When analyzing the data obtained during the analysis of liquid pyrolysis product and its fractions, as well as on the basis of published data, possible chemical reactions occurring during vulcanized rubber pyrolysis are proposed. Research results show that pyrolysis products are valuable chemical raw materials that have great prospects for industrial use, including the production of synthetic motor fuels.

The process of tar thermal cracking in a mixture with crushed oil shale to obtain components of motor fuels and raw materials for the process of thermal cracking is investigated in this paper. The optimization results of technological parameters (shale concentration, temperature, and duration) are presented and the material balance (mass.%) of the process is made. It was found that during single-stage processing under relatively mild conditions (5 MPa, 425C, feed space velocity of 1.0 h-1), a deep destruction of tar is achieved (the yield of the gasoline fraction from boiling point to 200C is ~12 wt.%; medium distillates with boil. point 200370C-43-44 mass.%; raw materials for thermal cracking with boil. point above 370C ~15-16 wt.% on per the original tar). The generating coke-like products and the V and Ni contained in the raw materials are deposited on the mineral part of the shale and removed from the reaction zone with the liquid products of the process.
