摘要: Natural and synthetic micorporous crystalline minerals that have a robust three-dimensional framework are modified by treatment with a molten salt that contains a component that reacts with the framework. Highly siliceous ZSM-5 and some aluminum phosphate compositions are catalytically activated by this method.

摘要: A method is disclosed for modifying an aluminosilicate-containing inorganic solid having a predetermined ion exchange capacity and containing an extractable silica by contacting, in the absence of added organic nitrogen or organic phosphorous compound and added activating metal oxide, the porous solid with liquid water at a pH of at least 6, at a temperature of up to 370.degree. C. for about 1 to 100 hours, and recovering a crystalline solid having an ion exchange capacity greater than the starting inorganic solid.

摘要: Alumina-composited zeolite catalysts are activated by contact with an aqueous ammonium solution under ammonia gas pressure such that a pH of at least about 10 is maintained in the solution. The treated zeolite may thereafter be calcined without prior ammonium-exchange to provide the zeolite in the hydrogen form.

摘要: Alumina-composited zeolite catalysts are activated by contact with an aqueous ammonium solution under ammonia gas pressure such that a pH of at least about 8 is maintained in the solution. The treated zeolite may thereafter be calcined without prior ammonium-exhange to provide the zeolite in the hydrogen form. Catalysts which are activated in this manner are useful for converting alcohols and/or ethers to hydrocarbons including aromatics.
