Abstract: The present invention relates to molecular sieve compositions and a process to synthesize such compositions. More particularly, this invention relates to a catalyst composition with metal oxide deposited on the exterior surface of the molecular sieve particles. The metal oxide can be deposited by contacting the molecular sieve particles with a solution of a metal-containing salt and a solvent, the metal-containing salt solution having an anion size larger than the pore size of the molecular sieve particles. The molecular sieve particles can then be dried and then treated under conditions sufficient to form a metal oxide, whereby at least a portion of the metal-containing salt can be converted to metal oxide.

Abstract: An oxygenate conversion catalyst useful in the conversion of oxygenates such as methanol to olefinic products may be improved by the use of a catalyst combination based on a molecular sieve in combination with a co-catalyst comprising a mixed metal oxide composition which has oxidation/reduction functionality under the conditions of the conversion. This metal oxide co-catalyst component will comprise a mixed oxide of one or more, preferably at least two, transition metals, usually of Series 4, 5 or 6 of the Periodic Table, with the metals of Series 4 being preferred, as an essential component of the mixed oxide composition. The preferred transition metals are those of Groups 5, especially titanium and vanadium, Group 6, especially chromium or molybdenum, Group 7, especially manganese and Group 8, especially cobalt or nickel. Other metal oxides may also be present. The preferred molecular sieve components in these catalysts are the high silica zeolites and the SAPOs, especially the small pore SAPOs (8-membered rings), such as SAPO-34. These catalyst combinations exhibit reduced coke selectivity have the potential of achieving extended catalyst life. In addition, these catalysts have the capability of selectively converting the hydrogen produced during the conversion to liquid products, mainly water, reducing the demand on reactor volume and product handling.

Abstract: This invention relates to processes for converting oxygenates to olefins and olefins to polyolefins. The processes include a step of pretreating molecular sieve used in the conversion of oxygenate to olefin with a dimethyl ether composition. Fresh or regenerated molecular sieve, which is low in carbon content, is contacted or pretreated with the dimethyl ether composition to form a hydrocarbon co-catalyst within the pore structure of the molecular sieve, and the pretreated molecular sieve containing the co-catalyst is used to convert oxygenate to a lighter olefin product.
