Patent ID: 8105481

Claim:
An alkylation process comprising contacting a first hydrocarbon feed comprising at least one olefin having from 2 to 6 carbon atoms and a second hydrocarbon feed comprising at least one isoparaffin having from 4 to 6 carbon atoms with a halogen-containing acidic ionic liquid catalyst under alkylation conditions to produce an alkylate gasoline having an organic halide content from 50 to 4000 ppm and contacting at least a portion of the alkylate gasoline with at least one molecular sieve having a pore size from 4 to 16 Angstrom under organic halide absorption conditions, whereby the organic halide is absorbed during the contacting to reduce the organic halide content by 97.1% or greater in the alkylate gasoline to an amount less than 40 ppm.
