摘要： A process for removing sulfur compounds from hydrocarbon feedstreams, particularly those boiling in the naphtha range, by contacting the feedstream with an adsorbent comprised of cobalt and one or more Group VI metals selected from molybdenum and tungsten on a refractory support. This invention also relates to a process wherein a naphtha feedstream is first subjected to selective hydrodesulfurization to remove sulfur but not appreciably saturate olefins. A product stream is produced containing mercaptans that are removed by use of the cobalt-containing adsorbents of the present invention.

摘要： A method for selectively separating benzene from gasoline boiling range streams by first passing the stream to an adsorption zone comprised of an adsorbent capable of selectively adsorbing benzene from the stream. A substantially benzene-free stream results and the adsorbent is regenerated by treating it with a desorbent solvent capable of desorbing benzene from the solid adsorbent.

摘要： A totally contained adsorption process for the substantial total removal and conversion of benzene to cyclohexane in gasoline boiling range streams. At least a portion of the gasoline boiling range stream is passed through an adsorption zone containing an adsorbent which will selectively adsorb benzene from the stream. The process is totally contained in the sense that substantially total conversion of benzene to cyclohexane is achieved without the need for added desorbent. The desorbent is cyclohexane which is generated in the process.

摘要： A process for providing distillate products which are substantially sulfur free, which process comprises subjecting a distillate stream to conventional hydrodesulfurization conditions including a catalyst comprised of a Group VI metal and at least one Group VIII metal on a refractory support. The hydrodesulfurized stream is then treated with a solid adsorbent material capable of adsorbing beta and di-beta-substituted dibenzothiophene sulfur compounds.

摘要： A method for selectively separating benzene from gasoline boiling range streams by first fractionating the stream to produce a C.sub.6 heartcut fraction which is then passed to an adsorption zone comprised of a bed of solid adsorbent material capable of selectively removing benzene from the stream. The absorbent is regenerated with a suitable desorbent, preferably toluene.
