An integrated process unit for making one or more alkylate products is provided. The integrated process unit includes (a) a dehydrogenation reactor; (b) a single alkylation reactor; (c) a separator, following the alkylation reactor, that separates effluent from the alkylation reactor into a catalyst phase and a hydrocarbon phase; (d) a distillation unit, following the separator, that receives the hydrocarbon phase and separates it into alkylate products, an unreacted paraffin phase, and an isoparaffin phase; (e) a first recycle line that feeds unreacted paraffin phase to the dehydrogenation reactor; and (f) a second recycle line that feeds isoparaffin phase to the alkylation reactor.

Natural gas liquid upgrading by ionic liquid catalyzed alkylation

We provide a process, comprising: a. dehydrogenating natural gas liquid to produce a mixture comprising olefins and unconverted paraffins; b. without further purification or modification other than mixing with an isoparaffin, sending the mixture to a single alkylation reactor; c. alkylating the olefins with the isoparaffin, using an ionic liquid catalyst, to produce one or more alkylate products; and d. distilling the one or more alkylate products and collecting a bottoms distillation fraction that is a middle distillate blending component having a sulfur level of 50 wppm or less and a Bromine number less than 1.
