ABSTRACT:
A process for producing a low volatility gasoline blending component and a middle distillate, comprising alkylating a hydrocarbon stream comprising at least one olefin having from 2 to 6 carbon atoms and at least one paraffin having from 4 to 6 carbon atoms with an ionic liquid catalyst and an unsupported halide containing additive, and separating the alkylate into at least the low volatility gasoline blending component and the middle distillate, wherein the middle distillate is a fuel suitable for use as a jet fuel or jet fuel blending component. Also, a process for producing a gasoline blending component and a middle distillate, comprising adjusting a level of a halide containing additive provided to an ionic liquid alkylation reactor to shift selectivity towards heavier products, and recovering a low volatility gasoline blending component and the middle distillate. Also, processes comprising alkylating isobutane with butene over specific chloroaluminate ionic liquids.
