(54) METHOD OF CARRYING OUT FISCHER-TROPSCH SYNTHESIS (VERSIONS)
(57)
FIELD: industrial organic synthesis. SUBSTANCE: invention relates to synthesis of saturated and unsaturated hydrocarbons with preliminary separation of multicomponent, multiphase mixtures leaving reactor into desired- composition fractions, formation of constant liquid reaction medium, and optimization of Fischer-Tropsch process. Carbon monoxide and hydrogen are fed into reactor with liquid solvent and suspended catalyst therein. Condensation products are returned into reactor. Composition of return condensate is varied by varying dephlegmator temperature or varying percentage of condensed reaction products returned into reactor. To maintain fixed composition of solvent, amount and composition of liquid reaction products returned into reactor are controlled. EFFECT: enhanced process efficiency. 3 cl, 3 dwg, 1 tbl
