METHOD OF PROCESSING ALIPHATIC C2-C12-HYDROCARBONS INTO AROMATIC HYDROCARBONS OR HIGH-OCTANE GASOLINE |
摘要 |
petrochemical processes. SUBSTANCE: method includes heating raw material containing aliphatic C2-C12-hydrocarbons, bringing raw material into contact with catalyst containing pentasil-group zeolite in reaction zone under conversion conditions to form product flow containing aromatic hydrocarbons, isolation of liquid flow containing C5- hydrocarbons and gas flow containing aliphatic C2-C4-hydrocarbons. Method is distinguished by that contact of raw material with catalyst is accomplished at least in two zones with different conversion conditions: light components of raw material contact with catalyst in high-temperature zone at higher temperature than temperature, at which heavy components of raw material contact with catalyst in low-temperature zone of endothermic reaction; and flow of low-temperature zone products is conveyed to low-temperature reaction zone. EFFECT: increased efficiency of processing of gasoline and multicomponent raw material. 3 cl, 4 tbl |
