This patent describes a steam reforming process for converting hydrocarbon material to hydrogen gas in the presence of sulfur which consists of: adding steam to the hydrocarbon material and passing the steam and hydrocarbon material over catalyst material at elevated temperatures. The improvement comprises utilizing as a catalyst material high activity, sulfur tolerant catalyst of platinum supported on lanthanum stabilized alumina or magnesium promoted lanthanum stabilized alumina. It also describes a steam process for converting hydrocarbon material to hydrogen gas in the presence of sulfur which consists of steam to the hydrocarbon material over catalyst material at elevated temperatures. The improvement comprises utilizing as a catalyst material high activity, sulfur tolerant catalysts consisting essentially of iridium supported on lanthanum stabilized alumina or magnesium promoted lanthanum stabilized alumina. In addition a steam reforming process is described for converting hydrocarbon material to hydrogen gas in the presence of sulfur comprising adding steam to the hydrocarbon material and passing the steam and hydrocarbon material over catalyst material at elevated temperatures. The improvement comprises utilizing as a catalyst material high activity sulfur tolerant catalysts consisting essentially of palladium supported on lanthanum stabilized alumina or magnesium promoted lanthanum stabilized alumina.
