20080223213 | Adsorption Process To Recover Hydrogen From Feed Gas Mixtures Having Low Hydrogen Concentration - A process for selectively separating hydrogen from at least one more strongly adsorbable component in a plurality of adsorption beds to produce a hydrogen-rich product gas from a low hydrogen concentration feed with a high recovery rate. Each of the plurality of adsorption beds subjected to a repetitive cycle. The process comprises an adsorption step for producing the hydrogen-rich product from a feed gas mixture comprising 5% to 50% hydrogen, at least two pressure equalization by void space gas withdrawal steps, a provide purge step resulting in a first pressure decrease, a blowdown step resulting in a second pressure decrease, a purge step, at least two pressure equalization by void space gas introduction steps, and a repressurization step. The second pressure decrease is at least 2 times greater than the first pressure decrease. | 09-18-2008 |
20090162268 | Carbon Dioxide Separation Via Partial Pressure Swing Cyclic Chemical Reaction - A method for separating a reactive gas from a feed gas mixture is disclosed. The method includes reacting the reactive gas with a bed of reactive solid in an exothermic reaction to create a second solid and a product gas from which the reactive gas is depleted. The product gas is removed and the heat from the reaction is used to liberate the reactive gas from the second solid in an endothermic reaction which yields the reactive solid. The reactive gas is removed and sequestered. Heat reservoir material is included in the bed to retain the heat in support of the endothermic reaction. A device for executing the method having an insulated chamber holding the bed, as well as process units formed of multiple beds are also disclosed. The process units allow the method to be operated cyclically, providing a continuous flow of feed gas, reactive gas and product gas. | 06-25-2009 |

20140308176 | Removal Of Hydrogen And Carbon Monoxide Impurities From Gas Streams - Hydrogen and carbon monoxide impurities are removed from a dry gas comprising the impurities, wherein the dry gas is at least substantially free of carbon dioxide, by passing the dry gas with sufficient residence time, e.g. at least 1.5 s, through a layer of catalyst comprising a mixture of manganese oxide and copper oxide. The use of expensive noble metal catalysts to remove hydrogen may thereby be avoided. In addition, regeneration of the catalyst using oxygen-containing regeneration gas does not reduce the effectiveness of the catalyst. | 10-16-2014 |
