This invention relates to a process for the efficient production of power by the oxidation of carbonaceous or hydrocarbon fuels with minimal pollution of the atmosphere. In one of its more specific aspects, this object is accomplished by partial oxidation of the hydrocarbon or other carbon-containing fuels to produce a fuel gas, followed by partial oxidation of this fuel gas and finally complete combustion of the gaseous products of the second partial oxidation with the generation of power in stages following each of the oxidation steps such that the stack gas discharged to the atmosphere is low in oxides of nitrogen and is substantially free from sulfur compounds. The process is particularly suitable for use with sulfur-containing petroleum residua, shale oils and the like.

In a process for the generation of power from a liquid or solid sulfur-containing fuel wherein said fuel is subjected to partial oxidation with air or oxygen at elevated pressure effecting conversion of said sulfur-containing fuel to a fuel gas stream having a higher heating value in the range of 60

In a process for the generation of power from a liquid or solid sulfur-containing fuel wherein said fuel is subjected to partial oxidation with air or oxygen at elevated pressure effecting conversion of said sulfur-containing fuel to a fuel gas stream having a higher heating value in the range of 60 to 350 Btu\s per cubic foot and comprising carbon monoxide, hydrogen, methane and gaseous sulfur compounds, and said gaseous sulfur compounds are removed from said fuel gas stream, the improvement which comprises: (a) subjecting said fuel gas stream to partial oxidation with air at said pressure in the range of 300 to 500 psia and at a temperature in the range of 1500°to 2500°F. effecting conversion of said fuel gas to a low heating value gaseous mixture comprising hydrogen and carbon oxides, said gaseous mixture comprising hydrogen and carbon oxides and having a higher heating value in the range of 40 to 233 Btu\s per standard cubic foot. (b) expanding said low heating value gaseous mixture from (a) in an engine to a pressure in the range of 30 to 50 psia producing power, (c) subjecting said low heating value gaseous mixture to substantially complete combustion with air at a pressure in the range of 30 to 50 psia producing flue gases comprising products of complete combustion, and (d) expanding said flue gases in an engine to substantially atmospheric pressure with the production of power.
