Abstract
A novel alkylation catalyst is described which is used in processes for alkylating olefin hydrocarbons with isoparaffin hydrocarbons to produce high octane alkylate products suitable for use as a blending component of gasoline motor fuel. The novel catalyst comprises a mixture of a Lewis acid, a strong Bronsted acid, and a predominant amount of a weaker acid. The novel alkylation catalyst is utilized in a novel process for alkylating olefin hydrocarbons with isoparaffin hydrocarbons. Specifically the novel catalyst comprises antimony pentaflouride, trifluoromethanesulfonic acid and a predominant amount of methanesulfonic acid.
