Abstract: A process and apparatus are disclosed for the operation of a compact water gas shift reactor for use in conjunction with fuel cell to generate electric power from a feed stream comprising a hydrocarbon or an alcohol. The fuel cell comprises a proton exchange membrane which produces electric power from a hydrogen product stream which comprises essentially no carbon monoxide. The hydrogen product stream may produced from the feed stream in a steam reforming of autothermal reforming zone. The compact water gas shift reactor comprises a vertically aligned vessel having a top end, a bottom end opposite, which defines an interior space. The interior space contains a first water spray zone for contacting a reforming effluent stream comprising hydrogen with a first water stream. A first dispersion zone is disposed below the first water spray zone and above a high temperature shift zone. The high temperature shift zone contains a high temperature shift catalyst to produce a high temperature shift effluent stream.

The gas to be purified can be any gas, such as synthesis gas or natural gas, which contains gaseous, acidic impurities such as CO2, H2S, SO2, CS2, HCN, COS or mercaptans. The absorption liquid comprises: A) from 0.01 to 4% by weight of at least one compound of the formula B) from 0.001 to 8.0% by weight of water, and C) at least one polyalkylene glycol alkyl ether of the formula R1—O—(R2—O)x—R3 to 100% by weight, where R1 is C1-C4-alkyl, R2 is ethylene or 2-methylethylene, R3 is hydrogen or C1-C4-alkyl, R4 is hydrogen or C1-C4-alkyl, R5 is C1-C4-alkylene and X is an integer from 1 to 10. The amine may be N-methyldiethanolamine and the ether may be polyethylene glycol dimethyl ether.

The contacting is conducted at a temperature of 300° C. or less.

Abstract: An efficient method for producing a hydrogen-containing gas for a fuel cell by using a gas produced by reforming reaction of an organic compound is disclosed. The method comprises the following steps: adding an oxygen-containing gas to a hydrogen-containing gas containing carbon monoxide to form a mixed gas, and bringing the mixed gas into contact with a catalyst comprising a ruthenium metal as a main component and having a carbon monoxide adsorption of not less than 1 mmol/g-ruthenium and a carbon monoxide adsorption index of not less than 0.5, to thereby oxidize and remove carbon monoxide.
