摘要： PURPOSE:To reduce the energy required for separating and recovering concd. CO by separating the reformed gas obtained by the reaction of hydrocarbons with steam and gaseous CO2 by pressure-swinging adsorptive separation. CONSTITUTION:The hydrocarbons 6 are introduced into a reforming furnace 1 along with a CO2-rich gas 7 as the by product, allowed to react with steam 8 in the presence of a reforming catalyst 3, and reformed to obtain the reformed gas 9 contg. H2, CO2, CO, CH4, etc. The reformed gas 9 is then introduced into a pressure-swinging adsorptive separator(PSA) device 4, and separated into the gas 7 and a gaseous mixture of CO and H2. The gas 7 is returned to the furnace 1, and the gaseous mixture is separated into high-purity gaseous CO 10 and an H2-rich gas 11. The gaseous CO 10 is recovered as a product, and a part of the gas 11 is supplied to the furnace 1 along with the air 12, burned, and used as the heat source necessary for the reforming reaction. The remainder is supplied to a gas-turbine generator 5, and used as the power source.

摘要： PURPOSE:To separate and recover carbon monoxide in a feedstock gas in a high concentration with a small number of steps and power by subjecting a mixed gas, etc., obtained by reforming or partially oxidizing a hydrocarbon compound to specific treatment using a pressure swing adsorption separator. CONSTITUTION:A mixed gas obtained by reforming or partially oxidizing a hydrocarbon compound or by-product gas, such as converter gas, is introduced into a pressure swing adsorption separator, then adsorbed in an adsorption column in the separator to afford a hydrogen- or nitrogen-rich gas passing therethrough. Decompression is subsequently carried out in the direction opposite to the gas flow direction in the above-mentioned adsorption step just before starting discharge of methane and carbon dioxide in a decompression step thereof. Thereby, a carbon dioxide-rich gas containing concentrated carbon dioxide and methane is obtained. Furthermore, the hydrogen- or nitrogen-rich gas obtained in the initial period of the decompression step in the forward direction of the aforementioned adsorption step is used to boost the pressure of the adsorption column.
