    摘要: There is provided a process for aromatics conversion by contacting a feed suitable for aromatics conversion under conversion condition and in the presence of a catalyst comprising ITQ-13. Examples of such conversion processes include isomerization of aromatic (xylenes) feedstock, disproportionation of toluene to benzene and xylenes, alkylation and transalkylation of aromatics, conversion of light paraffins and light olefins to aromatics, conversion of naphtha to aromatics, and conversion of alcohol to aromatics.

    摘要: In a process for isomerizing a feed comprising ethylbenzene and a mixture of xylene isomers, the feed is first contacted under xylene isomerization conditions with a first catalyst composition to produce an intermediate product having a higher para-xylene concentration than the feed, and then the intermediate product is contacted under ethylbenzene isomerization conditions with a second catalyst composition. The second catalyst composition comprises a hydrogenation-dehydrogenation component and a molecular sieve having 10-membered ring pores and is effective to selectively isomerize at least part of the ethylbenzene in the intermediate product to para-xylene and thereby produce a further product having a para-xylene concentration greater than the equilibrium concentration of para-xylene at said ethylbenzene isomerization conditions.

    摘要: There is provided a catalyst containing porous macrostructures comprised of: (a) a three-dimensional network of particles of porous inorganic material (e.g., zeolites); and, (b) at least one metal (e.g., a catalytically active metal). The particles of the at least one macrostructure occupy less than 75% of the total volume of the at least one macrostructure and are jointed together to form a three-dimensional interconnected network. The three-dimensional interconnected network will usually be comprised of pores having diameters greater than about 20 Å. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger (e.g., a polymer-based ion exchange resin) and a synthesis mixture (e.g., for zeolite formation) capable of forming the porous inorganic material and the at least one metal; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material. The metal-containing macrostructures find application in hydrocarbon conversion (e.g., hydrogenation, dehydrogenation, dehydrocyclization, isomerization, hydrocracking, dewaxing, reforming, conversion of alkyl aromatics, etc.) and in the reduction of emissions of hydrocarbons, carbon monoxide, and/or oxides of nitrogen from an internal combustion engine.

    摘要: A process is disclosed for selectively producing one or more aromatic compounds selected from benzene, toluene, para-xylene, meta-xylene, ortho-xylene, ethylbenzene and mixtures thereof from a feed containing C6–C20 hydrocarbons and/or C6–C8 alcohols. The feed is initially subjected to a chemical conversion step to increase the concentration of C6–C8 paraffin and/or olefin precursors of said one or more aromatic compounds and then resulting precursor-enriched feed is then contacted with a dehydrocyclization catalyst under conditions of temperature and hydrogen partial pressure sufficient to effect dehydrocyclization of said paraffin and/or olefin precursors. A product rich in the desired aromatic compound(s) can then be recovered from the dehydrocyclization effluent.
