二甲醚催化转化制甲苯的反应研究
, PP. 994-1000
Keywords: 二甲醚,催化转化,甲苯,wo3/hzsm-5
Abstract:
？在氧气气氛中，对氧化钨改性的不同分子筛催化剂上二甲醚（dme）转化反应进行了评价。结果表明，wo3/hzsm-5催化剂上dme可以高选择性转化为甲苯，对其反应工艺条件进行了优化，常压、290℃、dme/o2比为2：1时，二甲醚几乎完全转化，转化率为98.97%，甲苯的选择性达到39.71%。对催化剂结构和酸性进行表征，结果表明，zsm-5分子筛的孔道结构最有利于甲苯的生成，wo3的介入调整了hzsm-5分子筛表面的酸性活性位点分布，在氧气气氛中有效地抑制了副产物的生成，使产物中甲苯的选择性提高。
