    摘要: This invention relates to a process for producing zeolite-bound high silica zeolites and the use of the zeolite-bound high silica zeolite produced by the process for hydrocarbon conversion. The process is carried out by forming an extrudable paste comprising a mixture of high silica zeolite in the hydrogen form, water, silica, and optionally an extrusion aid, extruding the extrudable paste to form silica-bound high silica zeolite extrudates, and then converting the silica of the binder to a zeolite binder. The zeolite-bound high silica zeolite produced by the process comprises high silica zeolite crystals that are bound together by zeolite binder crystals. The zeolite-bound high silica zeolite finds particular application in hydrocarbon conversion processes, e.g., catalytic cracking, alkylation, disproportionation of toluene, isomerization, and transalkylation reactions.

    摘要: A xylene isomerization process is disclosed in which any ethylbenzene in the feed is removed, either by dealkylation or isomerization, in a separate reactor upstream of the xylene isomerization reactor and the xylene isomerization catalyst is contained in the same reactor, typically a clay treater, as that used to accommodate the olefin removal catalyst. In certain cases, a single catalyst may be used to effect both xylene isomerization and olefin removal.

    摘要: There is provided a process for converting hydrocarbons using a catalyst comprising macrostructures having a three-dimensional network of particles comprised of porous inorganic material. The particles of the macrostructures occupy less than 75% of the total volume of the macrostructures and are joined together to form a three-dimensional interconnected network 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 and a synthesis mixture capable of forming the porous inorganic material; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material.

    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.
