Abstract: Solution of ferric nitrate was obtained from industrial iron based on the following equation Fe+4HNO3→Fe(NO3)3+NO+H2O and 2NO+O2→2NO2. Fe-Cu-K-Si catalysts were prepared in a continuous precipitation reactor. Performance of No.16 catalyst prepared from Q-235 carbon steel is the best among three industrial irons: iron sheet, iron powder and Q-235. In the range of 265 ℃~276 ℃, 1.5 MPa~1.6 MPa, H2/CO 0.68~1.0 and WHSV 3.6 L/g·h~4.2L/g·h, the mean values of xH2+CO and C5+ are 68.7% and 96.7 g·m-3 in the evaluation test of 432 h. Performance of No.16 catalyst being lower than that of No.9 catalyst is due to effect of poison of P,S contained in industrial iron Q-235.-
