摘要： In a process for converting C 9 + aromatic hydrocarbons to lighter aromatic products, a C 8 + aromatic hydrocarbon feed is passed through a xylenes fractionation column to separate the feed into a C 8 rich vapor overhead fraction and a C 10 + rich liquid bottoms fraction. In addition, a vapor side-stream is removed from adjacent the bottom of the xylenes fractionation column and at least part of the vapor side-stream is passed through a condenser to condense a heavy liquid stream rich in C 10 and higher aromatics and leave a lighter vapor stream rich in C 9 and C 10 aromatics. The lighter vapor stream rich in C 9 and C 10 aromatics is then contacted with toluene or benzene in the presence of a trans alky lation catalyst system under transalkylation reaction conditions to produce a transalkylation reaction product comprising (i) benzene or toluene and (ii) xylene.

摘要： In a process for the production of para-xylene, an aromatic feedstock comprising toluene and/or benzene is reacted with methanol under alkylation conditions in a reactor in the presence of a fluidized bed of solid catalyst particles to produce a vapor phase effluent comprising para-xylene, water, unreacted toluene and/or benzene and solid catalyst fines. The vapor phase effluent is contacted with a liquid hydrocarbon quench stream under conditions to condense a minor portion of the vapor phase effluent and produce a condensate which contains at least some of the catalyst fines and which is substantially free of an aqueous phase. The condensate containing said catalyst fines is then separated from the remainder of the vapor phase effluent.

摘要： In a process for producing para-xylene , a feed comprising a mixture of xylene isomers, olefinic unsaturated contaminants and oxygenate contaminants is supplied to a para- xylene recovery unit to recover para-xylene and produce a para-xylene depleted residual stream. The para-xylene depleted residual stream is then contacted with a xylene isomerization catalyst in a xylene isomerization zone under liquid phase conditions effective to isomerize xylenes and produce an isomerized product having a higher para-xylene content than the para-xylene depleted residual stream. The isomerized product is then recycled to the para-xylene recovery unit. At least one of the feed, the para-xylene depleted residual stream and the isomerized product is contacted with a solid acid catalyst in a treatment zone under conditions effective to reduce the level of olefinic unsaturated contaminants and oxygenate contaminants therein and produce a treated stream.

摘要： In a process for producing para-xylene, a naphtha feed is reformed under conditions effective to convert at least 50 wt% of the naphthenes in the naphtha feed to aromatics, but to convert no more than 25 wt% of the paraffins in the naphtha feed, and thereby produce a reforming effluent. A first stream containing benzene and/or toluene is removed from the reforming effluent and is fed to a xylene production unit under conditions effective to convert benzene and/or toluene to xylenes. In addition, a second stream containing C8 aromatics is removed from the reforming effluent and is fed, together with at least part of the xylenes produced in the xylene production unit, to a para-xylene recovery unit to recover a para- xylene product stream and leave a para-xylene-depleted C8 stream. At least part of para- xylene-depleted C8 stream is then fed to a xylene isomerization unit effective to isomerize xylenes in para-xylene-depleted stream back towards an equilibrium mixture of xylenes and thereby produce an isomerization effluent. The isomerization effluent is then recycled to the para-xylene extraction unit.

The first and second isomerized streams are then recycled to the para -xylene recovery step.

摘要： A process for producing para-xylene (PX) comprises supplying a hydrocarbon feed comprising xylenes and ethylbenzene (EB) to a PX recovery unit, where a PX-rich stream and at least one PX-depleted stream are recovered from the feed. The PX-depleted stream is then separated into an EB-rich stream and an EB-depleted stream in a divided wall column. The EB-depleted stream is then isomerized under at least partial liquid phase conditions to produce a first isomerized stream having a higher PX concentration than the PX-depleted stream, and the EB-rich stream is isomerized under at least partial vapor phase conditions to produce a second isomerized stream having a higher PX concentration than the PX-depleted stream. The first and second isomerized streams are then recycled to the PX recovery unit to recover additional PX and the process is repeated to define a so-called xylene isomerization loop.

摘要： A simulated moving bed process using dual, parallel rotary valves configured or plumbed to be operated independently in which the step times of the rotary valves are staggered. In embodiments, the second rotary valve is programmed to step about halfway through the step time of the first rotary valve. Staggering the step time of the parallel rotary valves, rather than utilizing simultaneous stepping, results in increased net composite paraxylene concentration of the extract stream, allowing for increased capacity of the simulated moving bed process and/or reduced energy consumption.
