    摘要： Provided is a method for removing residual sulfur from a hydrotreated naphtha feedstock. The process comprises contacting the naphtha feedstock with a first solid sulfur sorbent comprising a metal on a support to thereby form a first effluent. The effluent is then contacted with a sulfur conversion catalyst comprising a Group VIII metal in the presence of hydrogen, with the resulting effluent being contacted with a second solid sulfur sorbent containing a Group IA or IIA metal, to thereby lower the sulfur content of the feedstock to less than 10 ppb, and to as low as 1 ppb or less. The feedstock can then be safely used with highly sulfur sensitive zeolitic reforming catalysts without adversely affecting the useful life of the catalyst.

    摘要： A process for producing gasoline components from a hydrocarbonaceous feed containing hydrocarbons comprising at least 4 carbon atoms is disclosed. The process comprises the following steps:a) separating feed into a heavy fraction containing hydrocarbons comprising at least 7 carbon atoms, an intermediate fraction containing mainly hydrocarbons comprising 6 or 7 carbon atoms, and a light fraction containing hydrocarbons comprising at most 6 carbon atoms,b) isomerizing at least part of the light fraction,c) combining effluent of step b) with the intermediate fraction, separating off a stream containing normal hydrocarbons and a stream containing branched hydrocarbons, andd) passing at least part of the stream containing normal hydrocarbons to isomerization step b).

    摘要： An improved aromatics extraction process is disclosed. Key feature of the present invention is use of the fractionator in the hydrodealkylation unit or other unit with a benzene fraction to fractionate not only hydrodealkylated benzene but also extracted benzene. The extracted benzene is used as "pseudo" reflux in the hydrodealkylation unit fractionator, thereby reducing the reflux requirement. The conventional re-run fractionator for clay treated benzene extract is eliminated, since polymerized olefins in this extract are removed as a bottoms fraction from the hydrodealkylation fractionator.
