Abstract

An aluminophosphate molecular sieve SCM-18 has a schematic chemical composition, expressed on a molar basis, of Al2O3.n P2O5, in which n represents a phosphorus to aluminum molar ratio, and is in a range of about 0.8-1.2. The aluminophosphate molecular sieve has a unique X-ray diffraction pattern, and can be used as an adsorbent, a catalyst or a catalyst carrier.
