Synthesis of the Вase Сomponent of Аviation Fuel from Synthesis Gas Obtained from Biomass

Abstract

We conducted a two-step synthesis of basic component of aviation gasoline from synthesis gas obtained by gasification of biomass. It is found out that a two-layer loading of methanol catalyst and γ-Al₂O₃ on the poor synthesis gas can be quite effective for getting dimethyl ether and methanol. The total conversion of CO per pass when using the gas with unfavorable for the oxygenates synthesis ratio of H₂/CO=0,96 amounted to 38,2 %, while the conversion of CO into CH₃OH was 15,3 %, and the conversion of CO into dimethyl ether was 20,9 %. It is shown that in the course of further conversion of oxygenates, high output of the base component in proportion to the missing oxygenates (44,6 %) was obtained, while there is also a high selectivity of liquid hydrocarbons that in the future will be used as a base component of aviation gasoline.
