Abstract
A composite material comprises: (a) a porous crystalline inorganic oxide material comprising a first framework structure defining a first set of uniformly distributed pores having an average cross-sectional dimension of from 0.3 to less than 2 nanometers and comprising a second framework structure defining a second set of uniformly distributed pores having an average cross-sectional dimension of from 2 to 200 nanometers and (b) a co-catalyst within the second set of pores of the porous crystalline inorganic oxide material (a).
Claims6
A process for converting a starting material into a product, the process comprising contacting the staffing material with a catalyst comprising a porous, composite material, which comprises:
- (a) providing a porous crystalline inorganic oxide material comprising a first framework structure defining a first set of micropores and comprising a second framework structure defining a second set of mesopores or macropores, wherein said micropores are occupied by a structure-directing agent, and said second set of pores are substantially free of structure-directing agent;
- (b) introducing a co-catalyst precursor in the second set of pores of said inorganic oxide material;
- (c) transforming the co-catalyst precursor into a co-catalyst;
- and
- (d) removing the structure directing agent from the micropores of the inorganic oxide material;
- (i) wherein the porous crystalline inorganic oxide material comprises a first framework structure defining a first set of uniformly distributed pores having an average cross-sectional dimension of from 0.3 to less than 2 nanometers and comprising a second framework structure defining a second set of uniformly distributed pores having an average cross-sectional dimension of from 2 to 200 nanometers;
- and
- (ii) the co-catalyst is selected from one or more of (1) at least one metal oxide different from said inorganic oxide material, (2) a phosphorus-containing compound, (3) a hydrogenation-dehydrogenation component, and (4) a microporous molecular sieve having a framework structure different from said first framework structure.

- (d) removing the structure directing agent from the micropores of the inorganic oxide material, thus forming a catalyst comprising a porous, composite material;
- and
- (e) contacting the starting material with the catalyst comprising a porous, composite material under conditions sufficient to at least partially convert the staffing material into the product.
