Nick A Collins, Jeffrey C Trewella: Alkylation process for desulfurization of gasoline. Mobil Oil Corporation, Ronald A Bleeker, Malcolm D Keen, February 4, 1997: US05599441 (25 worldwide citation)

Sulfur species present in cracked naphthas are converted and removed by first passing the naphtha over an acid catalyst to alkylate the thiophenic compounds in the naphtha using the olefins, i.e., monoolefins and diolefins, present in the naphtha as alkylating agent. Alkylated thiophenes are concent ...
