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.

Abstract: Methods and apparatuses for selective hydrogenation of olefins are provided. The method for selective hydrogenation of olefins comprises reacting a hydrocarbonaceous feedstock comprising olefins and aromatic compounds with hydrogen in a reaction zone. The reaction contains a catalyst producing a reaction zone product stream comprising aromatic compounds. The reaction zone product stream is passed to a flash vessel, recovering a first product stream and a second product stream from the flash vessel. The first product stream is passed to a liquid jet eductor, whereas the second product stream comprising aromatic compounds having a reduced concentration of olefins is subsequently recovered.

Abstract: Processes and apparatuses for isomerizing hydrocarbons are provided. In an embodiment, a process for isomerizing hydrocarbons includes providing a first hydrocarbon feed that includes hydrocarbons having from 5 to 7 carbon atoms. The first hydrocarbon feed is fractionated to produce a first separated stream that includes hydrocarbons having from 5 to 6 carbon atoms and a second separated stream that includes hydrocarbons having 7 carbon atoms. The first separated stream is contacted with a benzene saturation catalyst at benzene saturation conditions to produce an intermediate stream and subsequently isomerized in the presence of a first isomerization catalyst and hydrogen under first isomerization conditions to produce a first isomerized stream. The second separated stream is isomerized in the presence of a second isomerization catalyst and hydrogen under second isomerization conditions that are different from the first isomerization conditions to produce a second isomerized stream.

Abstract: A process for hydrotreating a coker kerosene feed stream to produce a feed stream for a paraffin separation zone. An effluent stream from a hydrotreating zone is passed to an aromatic separation zone to remove aromatics from the effluent stream form the hydrotreating zone and provide an aromatic lean stream. The aromatic lean stream may be passed to the paraffin separation zone to separate normal paraffins from non-normal paraffins. The separated aromatics can be passed to an aromatic processing zone to, for example, to produce xylene or other desirable aromatic hydrocarbons.
