摘要： A catalyst for converting C.sub.2 to C.sub.6 aliphatic hydrocarbons to aromatics is described. The catalyst contains a zeolite, an aluminum phosphate binder and a gallium component. Examples of zeolites which can be used are the ZSM family of zeolites, with ZSM-5 being a specific example. The catalyst is characterized in that it is tolerant to exposure to hydrogen at tempertures of about 500.degree. to about 700.degree. C. The catalyst's tolerance to hydrogen exposure is the result of treating the catalyst with an aqueous solution of a weakly acidic ammonium salt or a dilute acid solution at a temperature of about 50.degree. to about 100.degree. C. for a time of about 1 to about 48 hours, followed by calcination. A process for preparing the catalyst is also described.

摘要： This invention relates to a process for reactivating a dehydrocyclodimerization catalyst. Dehydrocyclodimerization catalysts which contain an aluminum phosphate binder can be deactivated when they are exposed to hydrogen at temperatures above 500.degree. C. The instant process restores substantially all of the catalyst's lost activity. The process involves treating the catalyst with an aqueous solution of a weakly acidic ammonium salt or a dilute acid solution at a temperature of about 50.degree. to about 100.degree. C. for a time of about 1 to about 48 hours. An ammonium nitrate solution is preferred. Next the catalyst is calcined at a temperature of about 500.degree. to about 700.degree. C. for a time of about 1 to about 15 hours to provide a reactivated catalyst. The catalyst can be reactivated several times using this process.

摘要： Alkyl aromatic compounds may be prepared by reacting an aromatic compound with an alkylating agent such as an olefin in the presence of an alkylation catalyst. The alkylation catalyst of the present invention comprises a composite which has been prepared by coextruding a clay component and at least one multi-valent metal component in which the metal is selected from the group consisting of Groups IIIA, IIIB and IVB of the Periodic Table, followed by drying the resultant extrudate and calcination thereof. By utilizing a catalyst which has been prepared by this method in an alkylation reaction it is possible to obtain an improved alkylate selectivity.

摘要： Alkyl aromatic compounds may be prepared by reacting an aromatic compound such as benzene with an alkylating agent such as an olefin or alkyl halide in the presence of an alkylation catalyst. The alkylation catalyst of the present invention comprises a clay which has been coextruded with a multi-valent metal and preferably a metal selected from the group consisting of Groups IIIA, IIIB and IVB of the Periodic Table. The resultant extrudate is then impregnated with a dissimilar multi-valent metal selected from the above named groups followed by calcination to form the desired composite. By utiilzing this catalytic composite in an alkylation reaction it is possible to obtain improved yields of alkyl aromatic compounds which may then be used in the preparation of biodegradable detergents.

摘要： A process for the desulfurization of hydrocarbonaceous oil wherein the hydrocarbonaceous oil is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone to reduce the sulfur level to a relatively low level and then contacting the resulting hydrocarbonaceous stream from the hydrodesulfurization zone with an oxidizing agent to convert the residual, low level of sulfur compounds into sulfur-oxidated compounds. The resulting hydrocarbonaceous oil stream containing the sulfur-oxidated compounds is separated after decomposing any residual oxidizing agent to produce a stream containing the sulfur-oxidated compounds and a hydrocarbonaceous oil stream having a reduced concentration of sulfur-oxidated compounds.
