  • Patent number: 4904518
    Abstract: This invention relates to multi-compositional, multiphase composite compositions comprising as phases thereof (i) an electronically conducting or semi-conducting substrate, (ii) an inorganic oxide composition layer in proximity to at least a portion of the surface of said electrically conducting or semi-conducting substrate and (iii) an inorganic crystalline molecular sieve composition layer upon at least a portion of the surface of said inorganic oxide composition layer. The inorganic crystalline molecular sieve composition layer is grown by crystal growth upon at least a portion of the inorganic oxide composition layer surface. The different phases of the composite compositions are substantially contiguous and exhibit a distinct compositional and/or structural heterogeneity of one phase to another.

  • Patent number: 4898660
    Abstract: A novel family of crystalline, microporus aluminophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures of aluminophosphate gels containing a molecular structure forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporus crystalline adsorbents with uniform pores, the dimensions of which vary, among the individual species, from about 3A to 10A diameter. The composition exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.
