MOLECULAR SIEVE COMPOSITIONS

摘要

MOLECULAR SIEVE COMPOSITIONS Crystalline molecular sieves having three-dimensional microporous framework structures of MO?, AlO2, and PO2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: mR : (MxAlyPz)O2 wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "M" represents iron and/or titanium, and at least one of cobalt, magnesium, manganese and zinc: "n" is 0. -1 or -2; "m" represents the molar amount of "R" present per mole of (MxAlyPz)O2; and "x", "y" and "z" represent the mole fractions of "M", aluminum and phosphorus, respectively, present as tetrahedral oxides. Their use as adsorbents, catalysts, etc. is also disclosed.
