1. An alkylation process comprising:
passing an isobutane feed and an ethylene feed to an alkylation reactor, wherein the alkylation reactor contains an ionic liquid catalyst, the ionic liquid comprising an organic cation and a halometallate anion, for reacting the isobutane and ethylene to generate an alkylate having a research octane number (RON) of 93 or more;
wherein the alkylation reactor is operated at reaction conditions including a temperature of from 30° C. to 100° C., a pressure of from 300 psig to 700 psig (2068 kPa to 4826 kPa), an overall isobutane to ethylene molar ratio from 2 to 20, and a residence time of from 5 minutes to 1 hour.
