磷酸硅铝分子筛SAPO-17的合成与性能研究

Studies on the Synthesis and Properties of Silicoalumihophosphate-17 Molecular Sieve

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。

Silicoaluminophosphate-17(SAPO-17) Molecular Sieve was synthesized by hydrothermal method. The X-Ray diffraction parameteres of the unite cell and chemical composition of SAPO-17 have been determined. The properties of SAPO-17 such as crystal morphology, thermal stability, adsorption capacity and catalytic activity have been studied.
