摘要： 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.

摘要： In a process for producing an essentially ash-free oil stock from a lubricating oil containing ash forming components comprising reacting the oil with an aqueous ammonium salt capable of reacting with the ash-containing components and heating the thus treated oil at a temperature in the range of about 300.degree. C. to about 420.degree. C. to increase the amount of the ash-forming components removed, the improvement comprising not exposing the oil to a temperature greater than 200.degree. C. before the oil is passed into a large volume of the oil already at a temperature in the range of about 300.degree. C. to about 400.degree. C.
