含氧化铝Zn H／ZSM-5催化剂芳构化反应性能的研究
Study on the reaction per formance of methanol to aromatics over Zn/HZSM-5 catalysts with alumina
摘要
Abstract
The present paper investigated the effect of Zn modified HZSM-5 catalysts on the reaction performance of methanol to aromatics with the presence of alumina.The catalysts were characterized by BET, XRD, Py-FTIR, NH3-TPD, and H2-TPR techniques, respectively.The experimental result demonstrated tha t the introduction of alumina produced mesopores in the HZSM-5 catalyst and strengthened the stability of Zn speic es on the sufr aceo f the caat lyst.The itn roduction of Zns pecei s broke the structure ofH ZSM-5 zeolite and changed the surface acidity oft eh catalyst.In da dition, Zn ps ecies might oc ntribute to the dehydrogena tion reaction of MTA.Meanwhli e, the subsequent aromatization procse s of olefins was impressed.Within the scope of this stdu y, the maximum vla ue of aromatic yield ( C6~11 ) reached 21.0%w hen the loading of Zn was 0.5%.The aromatization of methanol is at the control of coke on the catalyst.However,t he regenerated ac talyst exhibti ed a higher aromatic yield.关键词
