摘要： Provided are a high-performance desulfurizing agent for gases and a gas desulfurization method that provide a high desulfurization performance even at low temperatures and can maintain its desulfurization performance for a long period of time. The desulfurizing agent is characterized in that it includes a zinc oxide, an aluminum oxide and copper, the agent further including nickel by from 1.0 mass% to 10 mass% and ruthenium by from 0.1 mass % to 1.0 mass %. The gas desulfurization method is characterized in that the desulfurizing agent is brought into contact with the gas in the coexistent of hydrogen, thus decomposing/removing sulfur compound contained in the gas.

摘要： For implementing a reforming reaction such as steam reforming or autothermal reforming, to obtain hydrogen, carbon monoxide, carbon dioxide, methane, etc. by bringing hydrocarbons and steam into contact with a reforming catalyst, an arrangement is provided to enable reforming of the hydrocarbon to proceed under a stable condition for an extended period thanks to high sulfur resistance thereof. The arrangement employs a reforming catalyst supporting both platinum and iridium on an inorganic oxide support for the reforming of the hydrocarbon.

摘要： A reverse water-gas shift catalyst that can be used at high temperatures is obtained. A reverse water-gas shift catalyst (cat1) is produced by executing an impregnation-supporting step of impregnating a carrier (cb1) containing alumina as a main component with nickel as a catalytically active component (ca1) to be supported on the carrier, and calcinating a precursor obtained in the impregnation-supporting step at a temperature of 500°C or higher.

摘要： Provided are high-performance gas desulfurizing agent and desulfurizing method each of which has a high desulfurizing ability even at low temperatures and keeps its desulfurizing performance for an extended period of time. The gas desulfurizing agent includes zinc oxide, aluminum oxide, and copper, the desulfurizing agent further including nickel in an amount of 1.0% by mass to 10% by mass and rhenium in an amount of 0.1% by mass to 1.0% by mass. The gas desulfurizing method includes bringing the desulfurizing agent into contact with gas in coexistence of hydrogen to decompose a sulfur compound in the gas and remove the sulfur compound from the gas.
