摘要
利用连续和脉冲反应技术，考察了添加少量氧对丙烷在Ｇａ／ＨＺＳＭ－５上催化芳构化的影响。试验结果表明，氧的存在对丙烷转化为芳烃ＢＴＸ不利。通过进一步条件试验，对氧的作用进行了分析讨论，认为这与催化剂中活性组份镓的存在直接相关。
The effect of O_2 on propane aromatization over Ga/H2SM-5 is tested by continuous/pul-sative-reactor techniques. Addition of O_2 in the feeding gas strongly inhibits the conversion ofpropane to aromatic hydrocarbons. The role of O_2 is discussed in detail,and it is proposed that theoxygen effect is caused by the gallium active species in the catalyst.
