A sulfur-tolerant deoxidizer is studied in this paper. defferent gases such as H2,N2,Ar,and water-gas which contain 0.1-0.5%(vol%)O2 are tested.The results indicate that residual oxygen in gas product is less than 0.3 ppm(V)with space velocity 2000-30000h-1,reaction pressure 0.1-1.2MPa and reaction temperature 298-473K.Especially in gas containing H2S and H2,the residual oxygen is less than 0.1 ppm.For raw gases without H2,the capacity of deoxygenation can be up to 84ml/g.A long time operation for over 1000...
