Octane improvement process

Abstract From the Canadian patent

The octane number of light reformate is improved by alkylating the aryl compounds contained therein with olefins contained in a waste gas stream from a fluid catalytic cracking unit by contacting the light reformate with the waste gas in a catalyst bed. The catalyst structure in the catalyst bed acts as both a catalyst for the alkylation reaction and as distillation structure thus immediately separating the reaction product from the reaction zone to prevent reverse reactions and increase the overall reaction rate. The resultant product has an increased octane number and a lower specific gravity than the untreated light reformate.
