Abstract: We provide a process comprising: a. feeding a chlorinated-hydrocarbon and an ionic liquid catalyst to a treatment unit; b. operating the treatment unit at an elevated temperature to produce dechlorinated-hydrocarbon and HCl; and c. collecting the dechlorinated-hydrocarbon, wherein at least 90 wt % of the chlorides are removed. A second process comprises: a. creating an ionic liquid catalyst-rich zone in a distillation unit; b. passing chlorinated-hydrocarbon to the distillation unit; c. operating the unit under conditions causing removal of alkyl chloride to produce dechlorinated-hydrocarbon having a final boiling point close to a first final boiling point. A third process comprises: a. feeding alkylate gasoline blending component and ionic liquid catalyst to a treatment unit; b. operating the treatment unit; and c. collecting a dechlorinated-hydrocarbon, wherein at least 90 wt % of the chlorides have been removed and the dechlorinated-hydrocarbon has a second RON that is close to a first RON.

Abstract: A process for regenerating a used acidic catalyst which has been deactivated by conjunct polymers by removing the conjunct polymers so as to increase the activity of the catalyst is disclosed. Methods for removing the conjunct polymers include addition of a basic reagent and alkylation. The methods are applicable to all acidic catalysts and are described with reference to certain ionic liquid catalysts.

Abstract: A method and apparatus for alkylating an alkylation substrate with an alkylating agent in the presence of solid catalyst particles in a transport reactor is disclosed. Solid catalyst particles in the transport reactor effluent recirculate to the inlet of the transport reactor through one or more conduits. The rate through each conduit is regulated by fluid-controlled valves that use the alkylation substrate as the regulating fluid. This method and apparatus help ensure uniform or symmetric flow of catalyst from the effluent of the transport reactor to the bottom of the transport reactor. This method and apparatus also help ensure uniform or symmetric flow of alkylation substrate to the bottom of the transport reactor with minimal bypassing by the alkylating agent around of the transport reactor. This invention finds use in the production of motor fuels by the alkylation of liquid hydrocarbons in the presence of solid catalyst particles.

Abstract: Alkyl alcohols are added to the effluent from hydrocarbon reactions using phosphoric acid based catalysts to prevent corrosion in metallic pipes and vessels downstream of the reactor. The alcohol is believed to react with phosphoric acid present in the hydrocarbon stream to produce a mixture of phosphate esters which act as corrosion filmers to prevent corrosion. The high boiling points of the phosphate esters allow for the separation of useful product from the phosphate ester corrosion inhibitors.

Abstract: Hydrocarbons are alkylated in a fluidized riser-reactor using a solid catalyst which is regenerated within the process by contact with hydrogen. The alkylation and regeneration steps are separated to prevent the admixture of hydrogen and any olefins present in the process. Two separate modes of regeneration are performed simultaneously: a mild liquid-phase washing and a vapor-phase hot hydrogen stripping operation.

Abstract: This invention provides a method for separating 2,6-diethylnaphthalene from a mixture of diethylnaphthalene isomers by contacting said mixture with zeolite producing the same powder X-ray diffraction pattern as faujasite and the method can efficiently separate 2,6-diethylnaphthalene from ethylation reaction products containing diethylnaphthalene isomers.

Abstract: A process for preparing dinitrobenzophenones which comprises reacting benzene with ethylene in the presence of an alkylation catalyst to obtain an alkylation product containing unreacted benzene, ethylbenzene, polyethylbenzenes, 1,1-diphenylethane and heavier products, separating benzene, ethylbenzene and polyethylbenzenes from said alkylation product, recovering from the remainder of said alkylation product a fraction whose boiling points fall within the temperature range of about 260.degree. to about 290.degree. C., reacting said fraction with nitric acid at a temperature within the range of about 130.degree. to about 210.degree. C., wherein the molar ratio of nitric acid to said fraction is in the range of about 3:1 to about 8:1, and thereafter reacting the total resulting reaction product with nitric acid in oleum to obtain a nitration product predominating in dinitrobenzophenones.
