FIELD: petrochemical processes. SUBSTANCE: hydrocarbon synthesis stage is accomplished by bringing carbon oxides/hydrogen mixture into contact with catalyst comprising metal-containing component and acid component at elevated temperature and overpressure. Reaction mixture is then separated into a number of fractions including liquid hydrocarbon fraction. The latter or its mixture with recycle is brought into contact with hydrocarbon-conversion catalyst or with two different such catalysts. EFFECT: increased flexibility of process and extended range of target products produced. 15 cl, 4 tbl, 40 ex
