Patent ID: 7906700

Claim:
A process for improving alkylate quality of alkylation product, comprising introducing a feed comprising isobutene and an isoparaffin and absent sufficient non-isobutene olefins which negatively impact the alkylate quality of alkylation product produced such that isobutene comprises at least 50 wt-% of the olefin in the feed, in the form of droplets, into an acid catalyst to thereby produce said alkylation product, wherein the Sauter mean diameter of said droplets is greater than or equal to about 150 μm and is less than or equal to about 500 μm, and wherein: (i) the concentration of hydrocarbons having equal to or greater than nine carbon atoms per molecule in said alkylation product is less than the concentration of hydrocarbons having equal to or greater than nine carbon atoms per molecule in, and (ii) the road octane rating ((R+M)/2) of said alkylation product is higher than that of, an alkylation product produced in a process wherein the Sauter mean diameter is greater than about 500 μm.
