  • Patent number: 4881366
    Abstract: A process is disclosed for the production of power, particularly in the form of electricity from a carbonaceous fuel which comprises partially oxidizing the fuel with oxygen or an oxygen-containing gas to yield a gas stream containing carbon monoxide at supra-atmospheric pressure, expanding the said gas stream to produce power, and substantially completely combusting at least a major portion of the expanded stream with additional oxygen or an oxygen-containing gas to produce additional power, characterized in that, prior to expansion, the said gas stream is subjected to a carbon monoxide shift reaction whereby at least some of the carbon monoxide therein is converted into carbon dioxide and hydrogen, and in that at least some of the heat of such shift reaction is used to preheat the gas stream prior to expansion. By using the process, greatly reduced emissions of nitrogen oxdies can be achieved which will help reduce acid rain.
