Sulfuric Acid Alkylation

Sulfuric acid alkylation represents one of the two common processes (second is HF alkylation) used in the refining industry to produce high-octane products for gasoline blending. This process involves the reaction of isobutane with olefins, primarily propylene or butylene, resulting in the formation of branched, long-chain paraffins. Alkylate boasts not only a high-octane number but also possesses a low vapor pressure, making it a highly valuable component in gasoline blending.
