Abstract

The present invention relates to a metal silicoaluminophosphate molecular sieve MeAPSO with a RHO framework structure and a preparation method thereof. The metal silicoaluminophosphate molecular sieve is characterized in that: the metal atoms are at least one of vanadium, copper, molybdenum, zirconium, cobalt, manganese, magnesium, iron, nickel and zinc. The chemical composition of said metal silicoaluminophosphate molecular sieve in anhydrous state is expressed as: mR.nMe.(SixAlyPz)O2, where R represents template existed in molecular sieve micropores, m is the molar number of said template per one molar of (SixAlyPz)O2, m=0.1˜0.5; Me represents metal atom entering into said metal silicoaluminophosphate molecular sieve framework, n is the molar number of Me per one molar of (SixAlyPz)O2, n=0.001˜0.30. Said metal silicoaluminophosphate molecular sieve has ion exchange performance and adsorption performance. The catalyst prepared from said metal silicoaluminophosphate molecular sieve can be applicable to multiple hydrocarbon reactions, such as catalytic cracking, reforming, polymerization, alkylation, transalkylation, isomerization, dehydrogenation, hydrogenation and the like.
