Abstract:
A process for making products with low hydrogen halide, comprising: a) stripping or distilling an effluent from a reactor into a first fraction having an amount of hydrogen halide, and a second fraction having a reduced amount of hydrogen halide; wherein the reactor comprises: an ionic liquid catalyst having a metal halide, and a hydrogen halide or an organic halide; and b) recovering one or more product streams, from the second fraction, having less than 25 wppm hydrogen halide. In one embodiment the ionic liquid catalyst has metal halide; and the recovering recovers propane, n-butane, and alkylate gasoline having less than 25 wppm hydrogen halide. In another embodiment the recovering uses a distillation column having poor corrosion resistance to hydrogen halide; and the distillation column does not exhibit corrosion. There is also provided an alkylate gasoline having less than 5 wppm hydrogen halide, a high RON, and low RVP.
