Patent number: 4863697Abstract: A continuous process for alkylating an alkylatable hydrocarbon in the presence of a acid-type catalyst in which the alkylatable hydrocarbon is contacted with an alkylating agent in the presence of a catalyst in a reaction zone so as to alkylate the alkylatable hydrocarbon. The reaction product is separated in an acid settler vessel into an alkylate product phase, located in the upper portion of the first separation zone, and a catalyst phase located in the lower portion of the first separation zone. The catalyst phase is further separated into a first portion and second portion, such that the first portion is cooled and recycled for use in the alkylation reaction zone as a catalyst recycle, and the second portion is passed into a second separation zone, wherein the catalyst phase is further separated into a rerun catalyst stream containing acid-type catalyst and an acid soluble oil stream. The rerun catalyst stream is passed into the hydrocarbon phase of the acid settler vessel.Type: GrantFiled: May 17, 1988Date of Patent: September 5, 1989Assignee: Phillips Petroleum Co.Inventors: Paul D. Hann, Joe VanPool
