Abstract: A process for the desulfurization of hydrocarbonaceous oil wherein the hydrocarbonaceous oil is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone to reduce the sulfur level to a relatively low level then contacting the resulting hydrocarbonaceous stream from the hydrodesulfurization zone with an oxidizing agent to convert the residual, low level of sulfur compounds into sulfur-oxidated compounds. The resulting hydrocarbonaceous oil stream containing the sulfur-oxidated compounds is separated after decomposing any residual oxidizing agent by contacting the stream with an adsorbent material to adsorb the sulfur-oxidated compounds to produce a hydrocarbonaceous oil stream having a reduced concentration of sulfur-oxidated compounds. The spent adsorbent is regenerated and subsequently returned to adsorbent service.

Abstract: Improved processes for preparation of sertraline or sertraline analogs in high enantiomeric purity centers on resolution using simulated moving bed chromatography of isomeric racemic sertraline or sertraline analogs. Resolution is effected with high enantiomeric purity, and the undesired enantiomer may be racemized and recycled to the resolution phase to avoid loss.

Abstract: Improved processes for preparation of tetralones in high enantiomeric purity centers on resolution using simulated moving bed chromatography of a racemic tetralone derivative.

Abstract: A process for separating meta-xylene from a mixture containing meta-xylene, para-xylene, and ortho-xylene has been developed. The process involves contacting the mixture with zeolite Beta to effect the adsorption of the para-xylene, ortho-xylene, and ethylbenzene in preference to the meta-xylene and recovering the meta-xylene.

Abstract: A process to isomerize at least one normal or mono-methyl-branched alkane to form at least one multi-methyl-branched alkane has been developed. At least one normal or mono-methyl-branched is introduced to a reaction zone to form at least one multi-methyl-branched alkane. The reaction zone is located between a first and a second adsorption zone with the adsorption zones containing an adsorbent effective to selectively adsorb normal and mono-methyl-branched alkanes relative to multi-methyl-branched alkanes. A desorbent is introduced to the first adsorption zone and an effluent containing at least one multi-methyl-branched alkane is withdrawn from the second adsorption zone. After a period of time, the introduction of the desorbent is redirected to the second adsorption zone and concurrently the withdrawal of the effluent is moved to the first adsorption zone.
