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.

关键词: MSU-1, SBA-12, F-T合成, 钴基催化剂, 烃分布

Abstract: Novel cobalt catalysts supported on MSU-1 and SBA-12 are developed for F-Tsynthesis 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 C19+ 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 XRDand N2 adsorption-desorption show that the mesoporous structure of Co/HMS collapses after F-Tsynthesis, 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.

Key words: MSU-1, SBA-12, Fischer-Tropsch synthesis, Cobalt based catalyst, Hydrocarbon distribution
