摘　　要：本文研究了不同铁铬原料及铜和稀土助剂对铁基高温变换催化剂活性的影响,得出最佳的配方为Fe2O381%、Cr2O38%、CuO8%、CeO23%,在汽气比为0.6的条件下,按国标ZBG74001-89检测,该催化剂在350℃时CO转化率为41.0%.经实验验证,除具有较高的耐热活性以外,该催化剂还具有很好的抗F-T副反应能力.This paper studies the effect of different starting materia l,copper and rare-earth assistant on the activity of iron based catalyst for High-Temperature Water-Gas Shift Reaction,and found the best prescription:Fe2O3 81%,Cr2O3 8%,CuO 8%,CeO2 3%.The catalyst activity reach 41.0%(based on CO conversion) at 350 ℃ in testing standard ZBG74001-89(the ratio of steam to dry gas is 0.6).Moreover,the adaptability of the catalyst under low ratio of steam to dry gas is wonderful,and as long as the water-gas ratio is higher than 0.13 no by-product is found.
