FIELD: alternate fuel production and catalysts.
SUBSTANCE: synthesis gas containing H2, CO, and CO2 is brought into contact, in first reaction zone, with bifunctional catalyst consisting of (i) metal oxide component containing 65-70% ZnO, 29-34%, Cr2O3, and up to 1% W2O5 and (ii) acid component comprised of zeolite ZSM-5 or ZSM-11, beta-type zeolite or crystalline silica-alumino-phosphate having structure SAPO-5 at silica-to-alumina molar ratio no higher than 200, whereas, in second reaction zone, multifunctional acid catalyst is used containing zeolite ZSM-5 or ZSM-11 and having silica-to-alumina molar ratio no higher than 200.
EFFECT: increased selectivity with regard to C5+-hydrocarbons and increased yield of C5+-hydrocarbons based on synthesis gas supplied.
