Abstract
Both a process and an apparatus whereby a fuel with both a high carbon content, a relatively high sulphur content and a relatively low ash content, can be combusted without the release of potentially damaged amounts of carbon dioxide and sulphur dioxide are described. Further, the process and apparatus each provide an operation whereby the carbon dioxide and sulphur dioxide emissions form the combustion of a carbonaceous fuel with both a high carbon content and a relatively high sulphur content can each be recovered as a useable product. Typically the fuel is petroleum coke, or certain grades of anthracite, coal and natural gas.
