ABSTRACT:
A novel hydrocarbon alkylation process is disclosed wherein the feed hydrocarbons are dried to maintain the water content of the alkylation catalyst at less than 2.0 wt. %, where said alkylation catalyst is comprised of a mineral acid and an ether component selected from the group consisting of tert-butyl ether, methylphenyl ether, tert amylmethyl ether (TAME), or methyl tert-butyl ether (MTBE). This process also incorporates a method of regenerating at least a portion of the alkylation catalyst to prevent build-up of more than 15 wt. % of polymer products therein.
