    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.
