Аннотация:The air gasification of wood at increased pressure in the filtration combustion mode is experimentally studied. It is experimentally shown that increasing the pressure in the reactor (up to 3 atm) during the gasification of wood leads to an increase in the productivity of the experimental setup (by a factor of 1.6), a decrease in the quantity of tars formed (by a factor of 1.5), and a change in the concentrations of outgoing gases. Thermodynamic calculations of the effect of pressure at the stage of wood pyrolysis are carried out. With an increase in pressure from 1 to 9 atm, the volume concentrations of hydrogen and carbon monoxide decrease, while the volume concentrations of the water vapor and carbon dioxide increase. However, at a pyrolysis temperature of 1300 K, an increase in pressure has practically no effect on the composition of gaseous products.
