Abstract
Motor fuel alkylation in the petroleum refining industry refers to the acid-catalyzed conversion of C3-C5 olefins with isobutane into highly branched C5-C12 isoparaffins collectively called alkylate, a valuable gasoline blending component. Alkylation reactions are catalyzed by liquid and solid acids.닑 HF alkylation and sulfuric acid alkylation are the most widely practiced commercial motor fuel alkylation processes and are the focus of this section.닑 In recent years, considerable development effort has gone into solid acid catalysts and processes that mitigate the hazards associated with HF and H2SO4. Several of these processes have been offered commercially, but have not caught on because of high recycle isobutane requirements and high capital costs associated with catalyst regeneration.닑 A new wave of ionic liquid catalysts is currently nearing commercialization.
