| 摘 要： | 制备了一系列不同钌含量的ZrO2负载的钴基费-托合成催化剂,采用X-射线衍射,H2-程序升温还原分析方法研究了钌助剂对Co-ZrO2催化剂还原性的影响。结果表明,催化剂钴物种主要以Co3O4的形式分散在载体表面。催化剂中加入少量的Ru助剂有利于氧化钴的两步还原和残余硝酸钴的还原,增强了催化剂的还原度。

| Abstract: | ZrO2 supported cobalt Fischer-Tropsch synthesis catalysts promoted with different Ru loading were prepared by incipient wetness impregnation method.Using X-ray diffraction and hydrogen temperature programmed reduction techniques were used to investigate the effect of Ru on the composition,reducibility of catalysts.The results showed that the two-step reduction peaks of cobalt oxides and cobalt nitrates in TPR profiles shifted to lower temperature,indicating that Ru increased the reduciblity of both cobalt oxide and cobalt nitrates in the catalyst. |
