Some precipitated iron catalyst is prepared, the contents of which consist of Quartz-SiO 2,Hermatite-Fe 2O 3 and Fe 2O 3-Iron Oxide. In an integral fixed-bed reactor, the Fischer-Tropsch synthesis is investigated on the precipitated iron catalyst. The catalytic performance of the precipitated iron catalyst is studied under different reaction conditions such as the temperature, space velocity and H 2/CO ratio.The experimental results show that:CO conversion and H 2 conversion increase, but CO 2 selectivity decreases,with the change of reaction temperature from 260 ℃ to 290 ℃, under the conditions of p = 2.6 MPa, GHSV = 800 h -1 , n (H 2)/ n (CO)=2/3. CO conversion and H 2 conversion decrease, but CO 2 selectivity increases under the condition of t =280 ℃, p =2.6 MPa, n (H 2)/ n (CO) =2/3;1/1;2/1, with the change of space velocity from 400 h -1 to 800 h -1 and t =290 ℃, p =2.6 MPa, n (H 2)/ n (CO) =2/3 with the change of space velocity from 2 400 h -1 to 6 400 h -1 .CO conversion,the usage ratio of H 2/CO and CH 4 selectivity increase,H 2 conversion and CO 2 selectivity decrease under the condition of t =280 ℃, p =2.6 MPa, GHSV=400 h -1 ,650 h -1 ,800 h -1 , n (H 2)/ n (CO) from 0.7 to 2.0.
