Isoparaffin-olefin alkylation with hf alkylation and isomerization in a

Abstract

A process for producing hydrocarbon alkylate from an isoparaffin and an olefin-acting agent. The isoparaffin, the olefin and a first, relatively low strength hydrogen fluoride catalyst are contacted in an alkylation reaction to form a reaction mixture, the reaction mixture is settled to separate a first hydrocarbon phase from the low strength catalyst phase, the first hydrocarbon phase is admixed with a second, relatively higher strength hydrogen fluoride catalyst phase in an alkylation soaker, the effluent from the soaker is settled to separate a second hydrocarbon phase from the high strength catalyst phase, and the hydrocarbon alkylate is recovered from the second hydrocarbon phase.
