Crystalline microporous solids consisting of FAU-type aluminium phosphates substituted with a metal or possibly with silicium, synthesis and application thereof

摘要

New microporous crystalline solids comprising aluminophosphates substd. in the framework by a metal Me (MeAPO) or by a metal Me and silicon (MeAPSO) of the type having a molar compsn. of the framework which, expressed as oxide, is defined by the formula (MexAlyPz(O)2 for the MeAPO and (MexAluPvSiw)O2 for the MeAPSO, in which x,y,z,u,v and w represent the mol. ratios of the various elements where x = 0.001-0.15, y = 0.34-0.51, z = 0.49-0.51, u = 0.30-0.51, v = 0.30-0.51, w = 0.001-0.20, x+y+z = 1 and x+u+v+w = 1. The solids have a FAU type structure.
