| 摘 要： | 采用介孔分子筛MSU－1，SBA－12和HMS为载体，制得含钴质量分数为15％的催化剂。在原料气V（H2）／V（CO）＝2．0，T＝473－513K,p=2.0MPa,GHSV=500H^-1的F－T合成条件下，反应活性依Co/HMS,Co/SBA-12,Co/MSU-1顺序降低，高碳烃（C19^ )选择性以Co/HMS最低；Co/MSU-1和Co／SBA-12催化剂介孔结构在反应中相对稳定，Co/HMS介孔结构在反应后完全塌陷。

| Abstract: | Novel cobalt catalysts supported on MSU\|1 and SBA\|12 are developed for F\|T synthesis in a fixed bed reactor, and the reactivity of Co/MSU\|1 and Co/SBA\|12 is compared with that of Co/HMS. It is found that the selectivity of C\++\-\{19\} hydrcarbon product for Co/MSU\|1 and Co/SBA\|12 is higher than that of \{Co/HMS\} and the chain propagation ability of Co/MSU\|1 and Co/SBA\|12 is higher than that of \{Co/HMS\}. The results of XRD and N\-2 adsorption\|desorption show that the mesoporous structure of \{Co/HMS\} collapses after F\|T synthesis, but that of Co/MSU\|1 and Co/SBA\|12 is partly kept, the relative stable mesostructure may be benificial to the product chain propagation. |
