磷酸硅铝系列分子筛SAPO-n是美国联合碳化物公司于1984年首先合成,SAPO-17是其中的一种。作为一种新的分子筛,对其晶胞参数,吸附和催化性能及热稳定性等方面的研究,至今很少见有文献报道。本文考察了SAPO-17的合成条件、物化性能、热稳定性及裂解正十六烷和粗柴油的催化性能,并测定了它的晶胞参数。 SAPO-n series of silicate phosphate aluminum silicate is the United States Union Carbide company first synthesized in 1984, SAPO-17 is one of them. As a new molecular sieve, its unit cell parameters, adsorption and catalytic properties and thermal stability and so on, so far rarely reported in the literature. In this paper, the synthesis conditions, physico-chemical properties, thermal stability and catalytic properties of SAPO-17 cracking n-hexadecane and gas oil were investigated and its unit cell parameters were measured.
