中文摘要: |
采用沉淀法制备Ru-Zn催化剂,用扫描电镜(SEM)、透射电镜(TEM)和X射线衍射(XRD)等手段对其进行表征,研究了分别以聚乙二醇和聚乙烯吡咯烷酮作为添加剂,对Ru-Zn系催化剂催化苯加氢制环己烯性能的影响。结果表明,Ru-Zn催化剂的催化性能与催化剂制备过程中使用的添加剂存在密切关系;采用聚乙二醇制备的Ru-Zn催化剂,苯转化率42%时环己烯选择性达82.3%。该催化剂在循环使用5次后,环己烯收率仍保持在32%以上。 |
英文摘要: |
Ru-Zn catalysts were prepared by a precipitation method, and their structure and physico-chemical properties were characterized by SEM, XRD and TEM. The influence of additives (i.e., polyethylene glycol, polyvinylpyrrolidone) on hydrogenation performance was investigated. The results showed that the catalytic performance of Ru-Zn catalyst correlated to the additives used in the preparation process. It was found that the benzene conversion and cyclohexene selectivity were 42% and 82.3%, respectively for the Ru-Zn catalyst prepared with polyethylene glycol. After 5 cycles, the Ru-Zn catalyst still has above 32% of cyclohexene yield. |
