摘要： A composition for passivating metal contaminants in catalytic cracking of hydrocarbons includes a non-layered, ultra-large pore crystalline material with at least one peak at a position greater than about 18 Angstrom Units d-spacing with a relative intensity of 100, and a benzene adsorption capacity of greater than about 15 grams benzene per 100 grams anhydrous crystal at 50 torr and 25.degree. C., and a metal passivator incorporated within the crystalline material. A method for passivating contaminating metals uses the composition during catalytic cracking as an additive or as a component of the catalyst.

摘要： A membrane is used in combination with fractionation and hydrodesulfurization to reduce the sulfur content of hydrocarbon feeds, preferably sulfur-containing naphtha feeds. A membrane separation zone is employed to treat a fraction of effluent from a fractionation zone containing sulfur-containing non-aromatic hydrocarbons to produce a sulfur rich permeate and sulfur deficient retentate. The sulfur rich permeate and a second fraction of the fractionation zone, which contains sulfur-containing aromatic hydrocarbons, are further treated in a hydrodesulfurization zone. The stream from the hydrodesulfurization zone and the sulfur deficient retentate from the membrane separation zone are then processed as low sulfur hydrocarbon streams, especially those streams being processed in the manufacture of gasoline when the initial hydrocarbon stream is naphtha from a fluidized catalytic cracking unit.
