摘要： This invention relates to a process for making a germanium-zeolite without using fluoride compounds. The zeolite is preferably a MFI-type structure, most preferably a ZSM-5 MFI zeolite. The germanium-zeolite is synthesized essentially in the absence of fluoride compounds from an aqueous gel containing a silica source, a germanium source, an aluminum source and a structure directing agent in the presence of an acid which does not contain fluorine, such as sulfuric acid, acetic acid, nitric acid, phosphoric acid hydrochloric acid or formic acid.

摘要： Molecular sieves are prepared by forming a reaction mixture slurry, spray drying the reaction mixture slurry to form particles, and heating the spray dried reaction mixture at a temperature and pressure sufficient to cause crystallization of the molecular sieve. The reaction mixture contains an organic templating agent capable of forming the molecular sieve. The template may be added to the reaction mixture either by adding all of the template prior to spray drying, or by adding a portion of the template prior to spray drying with the remainder being added after spray drying.

摘要： The invention involves a process for production of macrostructures of a microporous material. The process is characterized by the fact that seeds formed in or introduced by ion exchange or adsorption to a porous organic ion exchanger with the desired size, shape and porosity are made to grow and form a continuous structure by further deposition of inorganic material from a synthesis solution under hydrothermal conditions. The organic ion exchanger can be eliminated by chemical destruction or dissolution and, in so doing, leaves behind an inorganic microporous structure with the size and shape of the employed organic ion exchanger.

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： An in-extrudate reaction mixture to be effectively crystallized is effectively crystallized to produce zeolitic or non-zeolitic molecular sieves. The reaction mixture is heated within a slowly rotating, double-walled reactor vessel wherein a heated medium is conducted within a space formed between the double walls of the vessel. Thus, the reaction mixture is contacted by a uniformly heated wall while being gently tumbled at low speed. The tumbling action serves to uniformly distribute the heat within the reaction mixture without subjecting the mixture to such shearing that could damage shaped particles. A relatively high quantity of reaction mixture can be handled in that way to maximize the production volumes and reduce production costs.

摘要： A process is described for the preparation of zeolitic catalysts in the form of microspheres, comprising zeolite and oligomeric silica, characterized by a high mechanical resistance. The process consists in subjecting to rapid drying the suspension, to which tetra-alkylorthosilicate is optionally added, resulting from the synthesis of zeolite by hydrothermal treatment at autogenous pressure of the reagent mixture containing tetra-alkylammoniumhydroxide as templating agent, and subjecting the product resulting from the drying to calcination.
