Novel Catalytic Material:SAPO Molecular Sieves

Xiaozhou Wang

Abstract

Silicon aluminum phosphate (SAPO) molecular sieves are microporous crystals with the structure of SiO_2AlO~-_2PO~+_2 tetrahedral units. SAPO have electronegative framework and exchangeable cation and Lewis acidity. SAPO is a novel class of catalytic materials which exhibit excellent shape selectivity, thermal stability and hydrothermal stability,which can catalyze hydrocarbon reactions.
