  • Alkylation of olefins utilizing mixtures of isoparaffins
    Patent number: 5583275
    Abstract: Disclosed is an alkylation process in which C.sub.3 to C.sub.5 olefins are reacted with an isoparaffin mixture of isobutane and isopentane in the presence of a catalyst. Varying the amount of isopentane present in the mixture can control and/or eliminate the amount of isopentane produced in the alkylation reaction. The disclosed reaction has an improved alkylation yield, and also produces an alkylate having a lowered Reid Vapor Pressure and results in lowered olefin content for reformulated gasoline.
