Catalytic alkylation process
Patent
·
OSTI ID:6543989
This patent describes an alkylation process, comprising: (a) reacting an alkylatable hydrocarbon with a hydrocarbon alkylating agent, in the presence of an acid-type catalyst and under alkylation conditions, in an alkylation reaction zone, thereby producing an alkylate; (b) passing the resulting effluent from the alkylation reaction zone into a first separation zone having an upper portion and a lower portion; (c) separating, in the first separation zone, the alkylation reaction zone effluent into (1) an alkylate product phase, located in the upper portion of the first separation zone, and (2) a catalyst phase containing acid-type catalyst and acid-soluble oil, located in the lower portion of the first separation zone. (d) withdrawing from the alkylate product phase in the upper portion of the first separation zone an alkylate product as a first hydrocarbon liquid stream or a second hydrocarbon liquid stream; (e) withdrawing from the lower portion of the first separation zone first and second portions of the thus separated catalyst phase; (f) cooling the thus withdrawn first portion of the separated catalyst phase; (g) recycling the thus cooled first portion of the separated catalyst phase to the alkylation reaction zone as a catalyst recycle.
