| 中文摘要 |
| 通过研究不同Co负载量的Co/Al2O3催化剂对CH4的CO2重整制合成气活性的影响,发现Co负载量为13%(Wt)的Co/Al2O3活性最好;同时,考察了反应温度、空速、还原温度等对催化剂活性和产物中CO/H2比例的影响。结果表明反应温度升高,CH4的CO2的转化率均增加,但随空速的增加而降低;还原温度在400℃时催化剂显示出的活性最好;产物中CO/H2比例,随反应条件不同而略有增减。 |
| 英文摘要 |
| In this paper, the effect of Co content,pretreatment conditions,space velocity and reaction temperature on the preformance of mathane reformed to synthesis gas by carbon dioxide over Co/Al2O3 catalysts has been investigated. It was found that Co/Al2O3 catalyst with Co content of 13%(wt)(i.e.13%wtCo/Al2O3)showed the best reform activity,decreasing space velocity and increasing reaction temperature improved the conversion of mathane and carbon dioxide. Catalysts also showed the best activity at reduced temperature at 400℃.The CO/H2 ratio of yieids increased with the space velocity increasing,decreased with reduced temperature and reaction temperature increasing. When enough Co content is loaded on Al2O3(eg.13%wtCo/Al2O3), catalysts will appeare longer life and stability of activity. |
