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 adding a small amount of oxygen on the catalytic aromatization of propane over Ga / HZSM-5 was investigated using continuous and pulsed reaction techniques. The experimental results show that the presence of oxygen is detrimental to the conversion of propane to aromatic BTX. Through further experimental conditions, the role of oxygen was analyzed and discussed, which is believed to be directly related to the presence of gallium in the active component of the catalyst.
