Sulfuric acid alkylation

Learn about sulfuric acid alkylation technology, available for license from ExxonMobil.

Upgrading light olefins and isobutane to alkylate offers refiners an opportunity to increase their crude barrel value. Alkylate is a superior gasoline blendstock due to its high octane and low vapor pressure. ExxonMobil’s proven Sulfuric Acid Alkylation technology reacts propylene, butylene and pentylene with isobutane to form high-value alkylate for gasoline blending.
