摘要： A method and an apparatus for removing sulfur hydrocarbon compounds from a naphtha stream and for simultaneously removing sulfur hydrocarbon compounds from two streams is described. A separator vessel having a top, a bottom, a primary feed inlet and a co-feed inlet is disposed vertically above the primary feed inlet. The separator vessel further includes a catalyst bed disposed between the co-feed inlet and the top. A primary feed stream comprising sulfur hydrocarbon compounds is delivered through the effluent inlet and a vaporized co-feed stream that also comprises sulfur hydrocarbon compounds is delivered through the co-feed inlet. Vaporized sulfur hydrocarbon compounds from the primary feed stream with the vaporized co-feed stream pass upwardly through the desulfurization catalyst bed. Sulfur hydrocarbon compounds from both primary feed and co-feed stream are at least partially converted to hydrogen sulfide and non-sulfur containing hydrocarbons in the catalyst bed.

摘要： A catalytic hydrocracking process wherein a hydrocarbonaceous feedstock and a liquid recycle stream is contacted with hydrogen in a hydrocracking reaction zone at elevated temperature and pressure to obtain conversion to lower boiling hydrocarbons. A liquid hydrocarbonaceous stream produced from the effluent of the hydrocracking reaction zone is fractionated in a first zone of a divided-wall fractionation zone to produce at least one liquid hydrocarbonaceous product stream and a liquid hydrocarbonaceous stream containing hydrocarbons boiling at a temperature in the boiling range of the feedstock and heavy polynuclear aromatic compounds. At least a portion of the liquid hydrocarbonaceous stream containing heavy polynuclear aromatic compounds is introduced into a second zone of the divided-wall fractionation zone to produce a stream rich in polynuclear aromatic compounds. At least another portion of the liquid hydrocarbonaceous stream containing hydrocarbons boiling at a temperature in the boiling range of the feedstock is recycled to the hydrocracking reaction zone.
