Abstract
We provide a method for making hydrocarbon products with reduced organic halide contamination, comprising: a. separating an effluent from an ionic liquid catalyzed hydrocarbon conversion reaction into: i. a hydrocarbon fraction comprising an organic halide contaminant and from greater than zero to less than 5000 wppm olefins; and ii. a used ionic liquid catalyst fraction comprising a used ionic liquid catalyst; and b. contacting the hydrocarbon fraction with an aromatic hydrocarbon reagent and an ionic liquid catalyst to reduce a level of the organic halide contaminant to from greater than zero to 20 wppm in a finished hydrocarbon product.
