摘要： A method of modifying a zeolite catalyst to increase para-xylene selectivity of the zeolite catalyst in toluene methylation reactions is provided. The method includes forming a slurry of a ZSM-5-type zeolite and an aqueous solution of a phosphorus compound. Water is removed from the slurry to provide a non-steamed, phosphorus treated ZSM-5 zeolite catalyst without deposition of phosphorus onto the catalyst by organophosphorus vapor deposition. The resulting non-steamed, phosphorus treated ZSM-5 zeolite catalyst has a pore volume of from 0.2 ml/g or less and provides greater than 80% para-xylene selectivity of mixed xylenes when used in toluene methylation.

摘要： A catalyst for use in aromatic alkylation, such as toluene alkylation with methanol, is comprised of a zeolite with pore size from about 5.0 to about 7.0 Å containing a hydrogenating metal. The catalyst may be used in preparing an alkyl aromatic product by providing the catalyst within a reactor. The catalyst may be contacted with an aromatic hydrocarbon and an alkylating agent in the presence of hydrogen under reaction conditions suitable for aromatic alkylation. The catalyst may also be treated to further increase its stability. This is accomplished by heating the hydrogenating metal loaded zeolite catalyst in the presence of a reducing agent prior to use in an aromatic alkylation reaction to a temperature of from about 400° C. to about 500 ° C. for about 0.5 to about 10 hours.

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： Aromatization of alkanes having one to four carbon atoms per molecule to aromatics, such as benzene, toluene and xylenes (BTX), uses a catalyst of a crystalline zeolite on which platinum has been deposited, specifically a platinum-containing ZSM-5. A byproduct of the process is a light gas fraction of methane and ethane. The use of a platinum-containing ZSM-5 catalyst in an alkane aromatization process, such as the Cyclar process, suppresses the formation of methane and increases selectivity to BTX. The high content of ethane relative to methane in the light gas fraction allows this process effluent to be a feedstream for a cracker.
