Alkylation process using chloroaluminate ionic liquid catalysts

A process for the production of high quality gasoline blending components comprising reacting a refinery stream containing isobutane with a refinery stream containing ethylene under alkylation conditions in the presence of a chloroaluminate ionic liquid catalyst comprising an hydrocarbyl substituted pyridinium halide or an hydrocarbyl substituted imidazolium halide of the general formulas A and B, respectively.

• where R=H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and X is a halide and preferably a chloride, and R1 and R2=H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and where R1 and R2 may or may not be the same.

A process for the production of high quality gasoline blending components comprising reacting a refinery stream containing isobutane and isopentane with a refinery stream containing ethylene under alkylation conditions in the presence of a chloroaluminate ionic liquid catalyst comprising an hydrocarbyl substituted pyridinium halide or a hydrocarbyl substituted imidazolium halide of the general formulas A and B, respectively.

• where R=H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and X is a halide and preferably a chloride, and R1 and R2=H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and where R1 and R2 may or may not be the same.
