Abstract: A process for hydrotreating coker kerosene is described. Instead of a post treat reactor, a smaller trim reactor zone which operates at a lower pressure than the post treat reactor is used downstream of the product stripper. The trim reactor uses a noble metal catalyst to reduce the BI of the stripped product to less than about 150, and desirably in the range of about 50 to about 100.

Abstract: A process for separating benzene from a reactor effluent in which the reactor effluent is passed to a first separation zone to separate the effluent into a bottom benzene lean stream and an overhead stream. The bottom benzene lean stream does not need to be processed further to remove benzene. The overhead stream may be cooled and is passed to a second separation zone in which it is separated into a bottom benzene rich stream and a second overhead stream. The bottom benzene rich stream contains at least 80% of the benzene from the reactor effluent. The operating temperature of the first separation zone is greater than the operating temperature of the second separation zone.

Abstract: A process for producing alkylaromatic compounds is described. The process involves utilizing at least a portion of the aromatic compound used to regenerate the alkylation catalyst in a spent alkylation reaction zone as a reactant in the active alkylation reaction zone. The process further includes utilizing a portion of the process stream leaving the alkylation zone as a recycle stream to the alkylation zone.
