摘　　要：针对转化催化剂还原的现状,提出了催化剂中镍的状态实际上与所处温度下的H_2O/H_2有关,为保证催化剂中镍充分彻底还原,H_2O/H_2应小于10,为此控制的水碳比应为5～7。此外讨论了还原温度及气氛对转化催化剂性能的影响,并用工业实例加以说明。Current status of reforming catalyst reduction is discussed. Following are pointed out that; status of Ni in the catalyst is related to the ratio of H2O/H2 which should be less than 10;ratio of water to carbon should be 5 - 7. The influence of reduction temperature and atmosphere are also discussed. Industrial examples are illustrated.
