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 feed stream comprising C6+ aromatic hydrocarbons is separated into a toluene-containing stream, a C8 aromatic hydrocarbon- containing stream and a C9+ aromatic hydrocarbon-containing stream. The toluene- containing stream is contacted with a methylating agent to convert toluene to xylenes and produce a methylated effluent stream. Para-xylene is recovered from the C8 aromatic hydrocarbon-containing stream and the methylated effluent stream in a para-xylene recovery section to produce a para-xylene depleted stream, which is then contacted with a xylene isomerization catalyst under liquid phase conditions effective to isomerize xylenes in the para-xylene depleted stream and produce an isomerized stream. The C9+-containing stream with a transalkylation catalyst under conditions effective to convert C9+-aromatics to C8- aromatics and produce a transalkylated stream, which is recycled together with the isomerized stream to the para-xylene recovery section.

摘要： In a process for converting C9+ aromatic hydrocarbons to lighter aromatic products, a C8+ aromatic hydrocarbon feed is passed through a xylenes fractionation column to separate the feed into a C8 rich vapor overhead fraction and a C10+ 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 C10 and higher aromatics and leave a lighter vapor stream rich in C9 and C10 aromatics. The lighter vapor stream rich in C9 and C10 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.
