Abstract
A apparatus for the catalytic alkylation of an isoparaffin with one or more olefins. Reactant hydrocarbons are passed in contact with a liquid catalyst such as hydrofluoric acid in a reaction zone. The hydrocarbon phase is allowed to separate from the catalyst phase in a settling zone, and a portion of the hydrocarbon phase is cooled and reintroduced to the reaction zone in a separate stream from that of the feed hydrocarbons. The alkylation apparatus by which the process is carried out includes a vertical reaction vessel, which in a preferred embodiment is 2 to 6 feet in height, a settling vessel, means for fluid flow from the reaction vessel to the settling vessel, a conduit for fluid flow between the upper part of the settling vessel and the reaction zone, and means for cooling fluid in this conduit.
