活性金属磷酸铝分子筛型催化剂的研究(Ⅰ)CdAPO-5催化剂的合成及催化活性

Studies on the Active Metal Aluminophosphate Molecular Sieve Type Catalyst (Ⅰ) Cadmium Aluminophosphate Molecular Sieve (CdAPO-5)

用水热法合成了磷酸镉铝分子筛型催化剂CdAPO-5。对新合成的样品进行了XRD、IR、DTA及TG分析,结果证明该样品具有分子筛结构。此外,还研究了CdAFO-5对乙炔气相水合反应的催化活性。

The cadmium aluminophosphate molecular sieve type catalyst was synthesized by means of hydrothermal method. The structure and thermal stability of cadmium aluminophosphate molecular sieve (CdAPO-5) was characterized by XRD, IR, DTA, and TG. The results show that the structure of CdAPO-5 is of the AIPO_4-5 type. The catalytic activity of CdAPO-5 for vapor-phase hydration of acetylene was investigated.
