    摘要： The present invention provides for an energy efficient process of producing hydrogen/carbon monoxide gas mixtures from one or more hydrocarbon gas streams treated in a syngas producing unit by utilizing a carbon dioxide removal unit that contains sorbent beds in which a magnesium based sorbent is transported and cycled between different beds for sorption and desorption of carbon dioxide. The carbon dioxide recovered during the process is recovered at high temperature and high pressure therefore allowing for at least a portion of the carbon dioxide stream to be recycled for further treatment with little or no compression of the stream.

    摘要： The present invention relates to a process for purifying a CO2 rich gas stream in a catalytic oxidizer. In this process, flammable contaminants that are present in the CO2 rich gas stream are oxidized when the CO2 rich gas stream is injected along with a precisely measured amount of substantially pure oxygen into the catalytic oxidizer. As a result, a purified CO2 rich gas stream is produced which depending upon the amount of oxygen injected contains only minor traces of residual oxygen or minor traces of the flammable contaminants. This process is useful for purifying high-pressure residue streams from membrane water-gas shift reactors, membrane reformers, or sorbent enhanced reformers, where the pressurized CO2 rich gas stream also contains amounts of hydrogen, methane, and carbon monoxide. The process is also suitable for purifying CO2 permeate streams from reverse selectivity polymeric membranes that are used to separate CO2 from gas mixtures that contain CO2, H2 and CH4. In a further embodiment of the present invention, the inlet and outlet temperature of the catalytic oxidizer can be controlled by recycling part of the purified CO2 rich gas stream to the catalytic oxidizer inlet and/or injecting additional fuel into the catalytic oxidizer. Thereby, a useful amount of heat can be extracted and returned for use anywhere in the CO2 generating process. The heat obtained via the present process may also be utilized in other processes.
