Molecular sieve compositions with aluminum, phosphorus and at least two other elements

摘要: Crystalline molecular sieves having three-dimensional microporous framework structure of MO 2 , AlO and PO tetrahedral oxide units are disclosed. These have an empirical chemical composition on anhydrous basis expressed by the formula: mR:(M.sub.x Al.sub.y P.sub.z)O.sub.2 wherein "R" represents at least one organic templating agent present in intracrystalline pore system; "m" molar amount per mole (M x Al y P z )O ; "M" two elements capable forming oxides selected from group consisting arsenic, beryllium, boron, chromium, gallium, germanium, lithium vanadium; "x", "y" 37 z" represent fractions "M", aluminum phosphorus, respectively, as oxides. Their use adsorbents, catalysts, etc. is
