Isoparaffin-olefin alkylation
First Claim
1. A method of improving the quality of an alkylate product produced by an alkylation process including contacting a hydrocarbon mixture containing olefins and isoparaffins with a catalyst consisting essentially of hydrogen fluoride and a sulfone to thereby produce said alkylate product, the method comprising the step of:
- incorporating water into said catalyst in an amount such that the octane of said alkylate product is higher than said alkylate product produced when said catalyst contains no water.

Abstract
A novel alkylation catalyst is described which is used in processes for alkylating olefin hydrocarbons with isoparaffin hydrocarbons to produce high octane alkylate products suitable for use as blending components of gasoline motor fuel. The novel catalyst comprises a mixture of a hydrogen halide, a sulfone and water and has suitable corrosion properties which permit its utilization in alkylation process systems. The novel alkylation catalyst is utilized in a novel process for alkylating olefin hydrocarbons with isoparaffin hydrocarbons.

5. A method of improving the quality of an alkylate product containing trimethylpentane produced by an alkylation process including contacting a hydrocarbon mixture containing olefins and isoparaffins with a catalyst consisting essentially of hydrogen fluoride and a sulfone to thereby produce said alkylate product, the method comprising the step of:
incorporating water into said catalyst in an amount such that the concentration of trimethylpentane in said alkylate product is higher than said alkylate product produced when said catalyst contains no water. - View Dependent Claims (6, 7, 8)
