Thermodynamic studies of the process of biomass gasification have been carried out, technological parameters have been determined that make it possible to obtain synthesis gas of the required composition. Steam-air gasification of pine sawdust was carried out at a laboratory gasification plant. It has been experimentally confirmed that by the method of steam-air gasification of sawdust, it is possible to obtain synthesis gas with a ratio of H2 / CO = 2.15, while the output of generator gas from 1 kg of sawdust was 1.74 m3. A high-performance bifunctional zeolite-containing catalyst for the synthesis of hydrocarbons has been developed. The performance of the catalyst for hydrocarbons C5+ - 132 kg/ (m3 / h) has been achieved.
Studies of the influence of temperature (230-250 °C, pressure (10,-2.0 MPa), active metal content (6-18% by weight) were carried out. to determine the optimal parameters of the Fischer-Tropsch synthesis. It is shown that for the synthesis of biofuels of the second generation, it is necessary to use steam-air conversion of biomass, and the stage of hydrocarbon synthesis is carried out using a Co/(Al2O3-70ZSM-5) catalyst containing 6.4% by weight. of the active metal, at a pressure of 2.0 MPa, a process temperature of 240 ° C, OSG = 1000 h-1 and a ratio of H2 / CO = 2 in the synthesis gas.
Full-cycle studies of the process of conversion of biomass (sawdust of pine species) into motor fuels were carried out, the properties of laboratory fuel samples were investigated. The main technological solutions for processing biomass into synthetic motor fuels on modular installations and the technological scheme of the modular installation have been developed, the material balance has been calculated (the capacity for synthetic liquid hydrocarbons is 10000 tons/year).
