摘　　要：探讨硫中毒机理,指出转化催化剂的硫中毒是催化剂上镍活性中心吸附H_2S后阻碍对反应物分子的吸附所致。硫的毒害深度取决于进入转化炉原料气的硫含量,并举例说明对硫化物分析检测的重要性和中毒催化剂的再生处理。Sulfur poison to reforming catalyst is: Catalyst's active center(Ni) is adsorpted with H2S. Reactive molecular' s adsorption is retarded. The poison intensity is affected by the sulfur content of the feed gas, operation condition and characteristic of the catalyst. Example is given to demonstrate the importance of sulfur analysis and the effect of catalyst regeneration.
