摘　　要：为了研究催化剂的孔道结构对FT合成产物的影响,分别制备了层状黏土结构的铁基催化剂、L沸石负载铁催化剂以及硅胶负载铁催化剂.对这3种催化剂分别用比表面积测定和XRD进行表征.并分别在FT合成条件为0.5 MPa,270℃,合成气H2∶CO=2∶1,合成气流量为34.5 SCCM的条件下,在连续搅拌釜式反应器中反应8 h,收集液相产物,分析产物中的成分,得出产物的碳数分布,且催化剂的FT合成产物的碳数分布与0#柴油十分接近.In order to investigate the influence of the carrier structure of the caralyst on FT synthesis product, three kinds of iron clay catalyst were produced. They are iron clay catalyst, iron loaded L zeolite catalyst and iron loaded silica gel catalyst. The three catalysts were characterized by XRD and BET. The condition of FT synthesis are 0.5 MPa,270 ℃,H2： CO =2：1 ,air current 34.5 SCCM, FT synthesis was done for 8h in a continuous stirred bed reactor to simulate the slurry bed reactor, then the liquid product is collected. The carbon distribution of the liquid product ferric radical catalyst with different carrier was compared. It shows that the carrier structure plays an important part in the capability of the catalyst.
