Abstract
Crystalline microporous solids of the aluminophosphate type consisting of MeAPO-FAU and MeAPSO-FAU with Me denoting a metal which can adopt tetrahedral coordination in an oxide, for example Co and Zn. The solids are synthesized by hydrothermal crystallization of a gel containing the elements Me, Al, P or Me, Al, P and Si and a structuring agent consisting of a mixture of tetrapropylammonium and tetramethylammonium cations. These solids can be employed in adsorption and also as catalysts in the conversion of organic compounds such as hydrocarbons.
