Abstract: A self-started OSRM (oxidative steam reforming of methanol) process at evaporation temperature of aqueous methanol for hydrogen production is disclosed. In the process, an aqueous methanol steam and oxygen are pre-mixed. The mixture is then fed to a Cu/ZnO-based catalyst to initiate an OSRM process at evaporation temperature of aqueous methanol. The temperature of the catalyst bed, with suitable thermal isolation, may be raised automatically by the exothermic OSRM to enhance the conversion of methanol.

Abstract: Provided herein is a modified cobalt oxide based catalyst that includes cobalt oxide and lanthanum. The lanthanum is dispersed within the cobalt oxide, wherein the lanthanum is about 5-20% by weight of the modified cobalt oxide based catalyst. The method of producing the lanthanum modified cobalt oxide based catalyst and its use in producing hydrogen are also disclosed.

Abstract: A self-started OSRM (oxidative steam reforming of methanol) process at room temperature for hydrogen production. In the process, an aqueous methanol and oxygen are pre-mixed. The mixture is then fed to a Cu/ZnO-based catalyst to initiate an OSRM process at room temperature. The temperature of the catalyst bed, with suitable thermal isolation, may be raised automatically by the exothermic OSRM to enhance the conversion of methanol. A hydrogen yield of 2.4 moles per mole methanol from the process may be obtained.

Abstract: A self-started process for hydrogen production, which comprises following steps: providing a gas mixture having a methanol/oxygen molar ratio less than or equal to 0.6; and conducting the gas mixture to flow through a Cu/ZnO-based catalyst bed. The Cu/ZnO-based catalyst contains copper, zinc oxide, aluminum oxide, manganese oxide and/or cerium oxide. The Cu/ZnO-based catalyst can initiate the POM reaction; then, the gas mixture will rise to a temperature of over 120° C., and the POM reaction generates a HRG at a reaction temperature of less than or equal to 180° C. The HRG contains less than 4 vol. % CO, and the POM reaction generates 1.8 moles hydrogen or more per 1 mole methanol consumed.

Abstract: A hydrogen production process with high hydrogen yield at a low temperature is described. First, an aqueous methanol solution with water/methanol molar ratio between about 0.75 and about 2.5 is pre-mixed with oxygen in an oxygen/methanol molar ratio not greater than about 0.5. The mixture is then directed to pass through an activated supported gold catalyst undergoing an oxidative steam reforming of methanol to generate a hydrogen-rich gas with CO content less than 1% at a low reaction temperature (TR>150° C.). Gold particles on active supported gold catalysts have been dispersed to a size of 6 nm or less. The oxidative steam reforming of methanol may generate more than 2 moles of hydrogen for each mole of methanol consumed.

Abstract: The Pd/Al2O3 catalyst displayed significant activity towards conversion of NO into N2 and O2 at T>1050° K. On modifying the catalyst with NaOH, the required operation temperature may be lowered to 900° K. The modified Pd/Al2O3 may be used in stationary factories and power stations, as well as catalytic converters for abatement of NOx emission. Calorimetric and temperature-programmed-desorption studies revealed that observed catalytic activity at 900° K. resulted from a formation of interfacial sites which strongly adsorb NO molecules.
