Alkylation – CDAlky® / CDAlkyPlus® / AlkyClean®

Alkylate is an excellent, high-octane blending component for motor gasoline, and is well-accepted in the marketplace. Alkylate is made by reacting light olefins, such as butylenes, from typical refinery sources; fluid catalytic cracking units, or from steam cracking units, with isoparaffins, such as isobutane, in the presence of an acidic catalyst.
