Process for the generation of power from carbonaceous fuels with minimal atmospheric pollution

摘要

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.
