Abstract
A method for reducing halide concentration in a hydrocarbon product having an organic halide content from 50 to 4000 ppm which is made by a hydrocarbon conversion process using an ionic liquid catalyst comprising a halogen-containing acidic ionic liquid comprising contacting at least a portion of the hydrocarbon product with at least one molecular sieve having pore size from 4 to 16 Angstrom under organic halide absorption conditions to reduce the halogen concentration in the hydrocarbon product to less than 40 ppm is disclosed.
