Abstract:
A process to produce a composition, said process consisting essentially of:(1) contacting(1.1) a zeolite,(1.2) an organic silicon compound,(1.3) a Group 14 metal compound, and(1.4) a phosphorus compound together to form a first mixture;(2) treating said first mixture to form a second mixture, wherein the temperature used in the treating step (2) is sufficient to remove substantially all of the water in said first mixture and to convert silicon compound and phosphorus compound to oxides up to about 1000.degree. C.;(3) contacting said second mixture with a binder that is a compound containing a Group 2, 13-15 element, to form a third mixture, where said binder comprises a compound that is an oxide, or a compound that is convertible to an oxide during step (5);(4) agglomerating said third mixture to form a fourth mixture; and(5) treating said fourth mixture to form said composition, wherein the temperature used in treating step (5) is sufficient to remove substantially all of the water in said fourth mixture and to convert said silicon compounds, said phosphorus compounds and said binder compounds to oxides up to about 1000.degree. C.
