炼厂气芳构化Zn基与Mo基催化剂的比较

Comparative Study of Supported Zn and Mo Catalysts for Aromatization of Refinery Gas

探讨了以未经任何预处理的炼厂气作原料气的芳构化反应。 结果表明，在不 同催化剂上，都 会发生 Ｃ２ ～ Ｃ４ 烃的裂解和芳构化反应，但没有观察到甲烷的转化。各催化剂性能差别较大， Ｈ Ｚ Ｓ Ｍ － ５ 和 Ｚｎ／ Ｈ Ｚ Ｓ Ｍ５ 催化剂具有较强的抗中毒能力，而 Ｍｏ 负载型催化剂易于中毒，部分 Ｒｕ 物种的存在可以增强 Ｍｏ 的抗中毒性能。

The aromatization of catalytic refinery gas without any pretreatment has been studied.It shows that there are cracking and aromatization reactions of C 2,C 3and C 4 hydrocarbons,but no conversion of methane is found.Zn/HZSM-5 catalyst is resistant to the poisoning of the reactant;while the Mo catalyst is subject to poisoning.The existence of some Ru species enhances the ability of the Mo catalyst to resist poisoning.
