摘    要:考察了反应温度和反应时间对混合碳四在SO42-/TiO2 /HZSM-5催化剂上芳构化反应的影响。结果表明,低温时主要为齐聚产物 ,随温度升高,BTX和芳烃的选择性和收率随之增加,但催化剂失活加快,优化的反应温度为360 ℃;同ZnNi/HZSM-5催化剂相比,要达到相同的BTX和芳烃收率,SO42-/TiO2 /HZSM-5催化剂可使反应温度降低150 ℃左右。讨论了混合碳四在SO42-/TiO2 /HZSM-5上的芳构化机理。

关 键 词:SO42-/TiO2  /HZSM-5  混合碳四  低温芳构化

Abstract:Aromatization of mixed C4 over SO42-/TiO2 /HZSM-5 was studied and influence of reaction temperature and reaction time was investigated. The results showed that, oligomers were the main product at low temperature; the yield of and selectivity to BTX and aromatics increased with temperature, but higher temperature caused quicker deactivation of the catalyst; optimum reaction temperature was 360 ℃; For the same yield of BTX and aromatics, reaction temperature over SO42-/TiO2 /HZSM-5 was 150 ℃ lower than that over ZnNi/HZSM-5. The mechanism for aromatization of mixed C4 over SO42-/TiO2 /HZSM-5 catalyst was discussed.
Keywords:SO4^-/TiOE/HZSM-5  mixed C4 fraction  low temperature aromatization
