PROCESS FOR THE PRODUCTION OF GASOLINE FROM FUEL GAS AND CATALYTIC REFORMATE

摘要

A process for the production of gasoline from a C4-fuel gas containing ethene and propene and catalytic reformate containing C6 to C8 aromatic hydrocarbons. The C4-fuel gas stream (28) is obtained by catalytic cracking of the heavy distillate fraction (7) obtained by distillation of a crude feed (1) in a distillation apparatus (2). The reformate C6 to C8 aromatic hydrocarbons in stream (15) is obtained by hydrotreating naphtha (5) in zone (9), followed by reforming in zone (13). The C4-fuel gas (28) and C6-C8 aromatic reformate (15) are mixed and contacted in a catalytic reactor (29) with a zeolite catalyst to convert ethene and propene in the fuel gas to C5+ aliphatic and aromatic hydrocarbon gasoline and to convert C6 to C8 aromatics in the reformate into C8 to C11 hydrocarbon gasoline. In a preferred embodiment, the process comprises maintaining a fluidized bed of zeolite catalyst particles in a turbulent reactor at a temperature of 316 to 399 DEG C (600 to 750 DEG F) and pressure of 790 to 825 kPa (100 to 250 psia).
