摘　　要：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℃, 1.5MPa～1.6MPa, H2/CO 0.68～1.0 and WHSV 3.6L/g·h～4.2L/g·h, the mean values of xH2+CO and C+5 are 68.7% and 96.7g·m-3 in the evaluation test of 432h. 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.Solution of ferric nitrate was obtained from industrial iron based on the following equation Fe+4HNO_3→Fe(NO_3)_3+NO+H_2O and 2NO+O_2→2NO_2.

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.
