摘要： The present invention is an improved process and apparatus for producing para-xylene, particularly with respect to a process that involves the methylation of toluene and/or benzene to selectively produce para-xylene, wherein streams having differing amounts of ethylbenzene are separately treated in the recovery of para-xylene. A first hydrocarbon feed comprising xylenes and ethylbenzene is provided to a first para-xylene adsorption section, and a second hydrocarbon feed comprising xylenes and less EB than the first hydrocarbon feed is provided to a second para-xylene adsorption section. Segregating the feeds with differing ethylbenzene contents increases the overall efficiency of the adsorption of para-xylene by the adsorption units. Efficiency and energy savings may be further improved by subjecting the lower-content ethylbenzene stream to liquid phase isomerization.

摘要： In a process for producing para-xylene, a toluene-containing stream is contacted with a methylating agent under conditions effective to convert toluene to xylenes and produce a methylated effluent stream. Para-xylene is recovered from the methylated effluent stream to produce a para-xylene depleted stream and part of the para-xylene depleted stream is contacted with a xylene isomerization catalyst under liquid phase isomerization conditions effective to produce a first isomerized stream, while part of the para-xylene depleted stream is contacted with a xylene isomerization catalyst under vapor phase isomerization conditions effective to produce a second isomerized stream. The first and second isomerized streams are then recycled to the para-xylene recovery step.

摘要： In a process and system for treatment of feed stocks comprising alkylating agent and metal salts, the metal salts are removed from the feedstock by an efficient combination of separations processes. The processes may take place in one or more stages, each stage taking place in one or more vessels. Such treatment processes may remove 99.9% or more of metal salts from a feedstock, while recovering 99.9% or more of the alkylating agent from the feedstock for use in an alkylation reaction, especially of aromatics such as toluene and benzene. Preferred alkylating agents include methanol and mixtures of carbon monoxide and hydrogen, for methylation of toluene and/or benzene. The methylation proceeds over an aluminosilicate catalyst and preferably yields para-xylene with 75% or greater selectivity.

摘要： A process for producing xylene comprises contacting a first feed comprising C9+ aromatic hydrocarbons, at least one C6-C7 aromatic hydrocarbon and hydrogen with a first catalyst composition to dealkylate at least part of the C9+ aromatic hydrocarbons containing C2+ alkyl groups and to saturate the resulting C2+ olefins to produce a second feed. The second feed is then contacted with a second catalyst composition under conditions effective to transalkylate at least part of the C9+ aromatic hydrocarbons with at least part of the C6-C7 aromatic hydrocarbon to produce a first product comprising xylene. Each of the first and second catalyst compositions is substantially free of amorphous alumina.

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.
