METHOD OF SYNTHESIS OF AROMATIC HYDROCARBONS FROM GASEOUS MIXTURE OF LIGHT HYDROCARBONS COMPRISING PROPANE AND BUTANE Russian patent published in 2002 - IPC

FIELD: organic chemistry, chemical technology, petroleum chemistry. SUBSTANCE: synthesis of aromatic hydrocarbons from gaseous mixture of light hydrocarbons comprising propane and butane involves condensation and absorption of at least part of raw components in its ejection with liquid hydrocarbon flow, stabilization of obtained liquid mixture of raw hydrocarbons and active flow of ejector, isolation of C₄-hydrocarbons mixture and circulating ejector active flow, contact of C₄-hydrocarbons mixture with catalyst of dehydrocyclodimerization under conditions of dehydrocyclo- -dimerization and obtaining flow of products containing aromatic hydrocarbons and isolation of aromatic hydrocarbons from the flow. Invention provides production of compressed raw without compressor using. EFFECT: improved and simplified method of synthesis. 2 tbl, 1 dwg
