A Ni-based steam reforming catalyst having excellent carbon deposition resistance and sintering resistance is provided. The steam reforming catalyst is constituted by including nickel as a catalytically active metal, lanthanum as a first co-catalyst component, manganese as a second co-catalyst component, and a carrier containing &#x3b3;-alumina as a main component.

Steam reforming catalyst

Provided is a method for removing COcomprising: supplying a gas to be processed containing CO, Nand Oto a feed side of a CO/Oselective permeation membrane within a temperature range of 15&#xb0; C. to 50&#xb0; C.; generating water vapor and supplying the water vapor to the CO/Oselective permeation membrane; selectively removing COfrom the gas to be processed by permeating COin the gas to be processed from the feed side to a permeate side of the COselective permeation membrane selectively to Oand Nin the gas to be processed; and using a COfacilitated transport membrane having CO/Oselectivity and CO/Nselectivity within the temperature range as the COselective permeation membrane, the COfacilitated transport membrane being configured with a hydrophilic polymer containing an amino acid and a deprotonating agent for preventing protonation of an amino group of the amino acid supported by a porous membrane, wherein a COconcentration in the gas to be processed is 3 mol % or less on a dry basis.

Method and apparatus for removing CO2

A power generation system comprises a fuel gas supply devicefor controlling methane concentration or carbon dioxide concentration in a mixed gas MG containing methane and carbon dioxide within a setting range for the concentration in the fuel gas of a gas engine, and for supplying the mixed gas MG to the gas engineas the fuel gas, and a gas concentration sensorfor measuring the carbon dioxide concentration or the methane concentration of the mixed gas MG. The fuel gas supply devicecomprises a carbon dioxide removal devicefor removing carbon dioxide in the mixed gas MG, and an operating condition control devicefor controlling an operating condition that affects an increase or decrease of a carbon dioxide removal rate of the carbon dioxide removal device, and the operating condition control devicecontrols the operating condition of the carbon dioxide removal devicebased on the measurement result of the gas concentration sensor, thereby controlling the concentration of methane and carbon dioxide in the mixed gas.

Power generation system

Provided is a facilitated COtransport membrane having an improved COpermeance and an improved CO/Hselectivity. The facilitated COtransport membrane includes a separation-functional membrane that includes a hydrophilic polymer gel membrane containing a COcarrier and a COhydration catalyst. Further preferably, the COhydration catalyst at least has catalytic activity at a temperature of 100&#xb0; C. or higher, has a melting point of 200&#xb0; C. or higher, or is soluble in water.
