ABSTRACT:
An integrated process for the simultaneous alkylation of at least one isoparaffinic hydrocarbon with at least one C.sub.4 olefinic hydrocarbon and at least one isoparaffinic hydrocarbon with at least one olefinic hydrocarbon selected from the group consisting of C.sub.3, C.sub.5 and higher olefinic hydrocarbons and mixtures thereof, comprising: contacting a first alkylatable hydrocarbon comprising an isoparaffinic hydrocarbon with a first alkylating agent comprising at least one olefinic hydrocarbon selected from the group consisting of C.sub.3, C.sub.5 and higher olefinic hydrocarbons and mixtures thereof in the presence of an acid-type catalyst, to alkylate said first alkylatable hydrocarbon; separating the effluent from the first alkylation reaction into a first alkylate phase and a first catalyst phase containing catalyst-soluble oil; recycling at least a portion of said first catalyst phase to said first alkylation reaction; contacting a second alkylatable hydrocarbon comprising an isoparaffinic hydrocarbon with a second alkylating agent comprising at least one C.sub.4 olefinic hydrocarbon in the presence of an acid-type catalyst, to alkylate said second alkylatable hydrocarbon; separating the effluent from the second alkylation reaction into a second alkylate phase and a second catalyst phase containing catalyst-soluble oil; recycling at least a portion of said second catalyst phase to said second alkylation reaction; and adding at least a portion of one of said first catalyst phase, said second catalyst phase or both of said first and said second catalyst phases to the other of said first catalyst phase and said second catalyst phase.
