Abstract: An alkylation process is described. The process involves alkylation of isobutane and ethylene in a loop reactor using an ionic liquid catalyst as a continuous phase. The alkylate typically has a research octane number of at least about 93, and the olefin conversion is typically at least about 95%.

Abstract: 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; andd. 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.

Abstract: A process, comprising: providing an olefin feed comprising pentenes, butenes, and isopentane; and alkylating the olefin feed with isobutane using acidic ionic liquid catalyst; wherein less than 5 mol % of C5 olefins in the olefin feed are converted to isopentane, and the alkylate gasoline has defined final boiling points and high RONs. A process comprising: alkylating an olefin feed comprising pentenes and isopentane, with isobutane using acidic ionic liquid catalyst; wherein less than 5 mol % of C5 olefins in the olefin feed are converted to isopentane; and wherein an n-pentane product yield is low. An alkylate gasoline, comprising less than 0.1 wt % olefins and aromatics, less than 1.8 wt % C12+ hydrocarbons, and greater than 60 wt % combined C8 and C9 hydrocarbons, wherein the trimethylpentane in the C8 hydrocarbons and the trimethylhexane in the C9 hydrocarbons are defined.
