摘要： A process to remove carbon dioxide from a gas stream using a cross-flow, or a moving-bed reactor. In the reactor the gas contacts an active material that is an alkali-metal compound, such as an alkali-metal carbonate, alkali-metal oxide, or alkali-metal hydroxide; or in the alternative, an alkaline-earth metal compound, such as an alkaline-earth metal carbonate, alkaline-earth metal oxide, or alkaline-earth metal hydroxide. The active material can be used by itself or supported on a substrate of carbon, alumina, silica, titania or aluminosilicate. When the active material is an alkali-metal compound, the carbon-dioxide reacts with the metal compound to generate bicarbonate. When the active material is an alkaline-earth metal, the carbon dioxide reacts with the metal compound to generate carbonate. Spent sorbent containing the bicarbonate or carbonate is moved to a second reactor where it is heated or treated with a reducing agent such as, natural gas, methane, carbon monoxide hydrogen, or a synthesis gas comprising of a combination of carbon monoxide and hydrogen. The heat or reducing agent releases carbon dioxide gas and regenerates the active material for use as the sorbent material in the first reactor. New sorbent may be added to the regenerated sorbent prior to subsequent passes in the carbon dioxide removal reactor.

摘要： Apparatus and process for removing carbon monoxide from a gas stream comprising a major portion of an inert gas and a minor portion of carbon monoxide are provided. The process involves contacting a feed gas stream with at least a primary metal oxide in a reaction zone of a reactor vessel at conditions effective to convert substantially all of the carbon monoxide to carbon dioxide, thus producing a purified gas stream consisting essentially of the inert gas and carbon dioxide and substantially free of carbon monoxide. This process has (inter alia) a particular application as a tertiary purification process for producing a more highly purified source of gaseous nitrogen from a source of nitrogen originally produced from a conventional membrane air separation system, wherein the oxygen concentration in the nitrogen stream my vary around a setpoint value, and then further (or secondarily) purified by converting excess oxygen in the nitrogen to carbon monoxide and carbon dioxide using a fuel gas/combustion process, wherein the carbon monoxide concentration varies due to varying oxygen concentration in the feed stream to the combustion process.

摘要： The present invention provides a technique of reducing the concentration of carbon monoxide included in a hydrogen rich gas, which is fed as a supply of gaseous fuel to fuel cells. It is required that the activity of a carbon monoxide selective oxidation reaction for reducing the concentration of carbon monoxide is kept at a sufficiently high level in a wider temperature range. A CO selective oxidation unit 34, which reduces the concentration of carbon monoxide included in a hydrogen rich gas fed to fuel cells 20, has a carbon monoxide selective oxidation catalyst that includes a second element, such as lithium, in addition to ruthenium as a primary component. This arrangement enables the activity of the carbon monoxide selective oxidation reaction in the CO selective oxidation unit 34 to be kept at a sufficiently high level in a wider temperature range.
