Abstract:
1. A process for producing a gasoline blending component and a middle distillate, comprising: a. reacting a hydrocarbon stream comprising at least one olefin having from 2 to 4 carbon atoms and at least one paraffin having from 4 to 6 carbon atoms with an ionic chloroaluminate liquid catalyst and a halide containing additive, wherein at one paraffin are alkylated with at least one olefin to produce an alkylate product; b. adjusting over time a level of said halide containing additive provided to an ionic liquid alkylation reactor to shift selectivity towards heavier products in an alkylate product; and c. recovering from the alkylate product: i. the gasoline blending component having a RON of 91 or higher and a RVP less than 17.2 kPa; and ii. the middle distillate having greater than 95 vol % C10+ and less than 1 vol % C43+; and wherein the middle distillate is from 20 to 50 wt % of the alkylate product.
