在经磷或镁化合物改质的、自行合成的Fu—1沸石催化剂上,考察了甲醇及二甲醚转化为低碳烯烃的反应,并用氨的程序升温脱附法表征了上述催化剂上酸的强度和分布,进而探讨了该类沸石催化剂的酸性与其反应性能之间的关系。
The conversion of methanol and dimethyl ether to light olefins was investigated on a self-synthesized Fu-1 zeolite catalyst modified with phosphorous or magnesium compounds. The catalytic activity of the above catalysts was characterized by temperature programmed desorption Strength and distribution, and then discussed the relationship between the acidity of this kind of zeolite catalyst and its reaction performance.
