Abstract:
1. A process for hydrocarbon conversion, comprising: a) distilling a hydrocarbon effluent, from a reactor comprising an ionic liquid catalyst having: a metal halide, and a hydrogen halide or an organic halide, into: b) recycling at least a portion of the first fraction, wherein the at least a portion comprises at least 5 wt % and less than 95 wt % of the hydrogen halide, to the reactor; wherein the reactor conducts a hydrocarbon conversion selected from the group consisting of paraffin alkylation, olefin dimerization, olefin oligomerization, aromatic alkylation, and mixtures thereof; and c) recovering a propane, a n-butane, and an alkylate gasoline, directly from the second fraction, all having less than 25 wppm of the hydrogen halide.
