研究了水蒸气存在条件下Ｍｏ／ＨＺＳＭ５ 沸石分子筛催化剂上的甲烷芳构化反应行为，发现水蒸气的引入可以明显地降低甲烷芳构化反应的起始温度，从而在较为温和的条件下实现甲烷的活化． 适量水蒸气的加入可以在一定程度上改善Ｍｏ／ＨＺＳＭ５ 催化剂的稳定性，过量水蒸气的引入则会抑制甲烷芳构化反应． 在反应温度为９７３ Ｋ 时，引入适量的水蒸气对芳构化反应产物的分布没有明显影响． 在低温条件下的甲烷芳构化反应过程中检测到有乙烯生成，该结果支持了甲烷芳构化反应可能经历了乙烯这一中间产物的机理． 实验结果还表明，水蒸气对催化剂上的积炭量没有明显的影响．
The behavior of methane aromatization on Mo / HZSM5 zeolite catalysts was investigated in the presence of water vapor. It was found that the introduction of water vapor can significantly reduce the initial temperature of methane aromatization reaction, and thus under milder conditions Activated methane. The addition of proper amount of water vapor can improve the stability of Mo / HZSM5 catalyst to a certain extent, while the introduction of excessive water vapor can inhibit the methane aromatization reaction. At the reaction temperature of 973 K, the introduction of an appropriate amount of water vapor has no significant effect on the distribution of the aromatization reaction product. Ethylene formation was detected during the methane aromatization reaction at low temperatures, and the result supports the mechanism that the methane aromatization reaction may have undergone the intermediate product of ethylene. The experimental results also show that water vapor has no significant effect on the amount of coke deposited on the catalyst.
