Abstract (en)

In a method of producing a clean gas from hydrocarbons, hot air and steam are mixed in a reaction zone with-carbonaceous residue, whereby carbon reacts with oxygen to form CO2 and CO under heat release. Hydrocarbon is added to release moisture and volatile and to have reacted volatile and carbon to CO and H2, the sulfur of the hydrocarbon being mainly converted into H2S. A sulfur sorbent is added and is converted into CaO, which CaO reacts with H2S and COS to solid CaS. At the exit of the reaction carbonaceous residue is separated from the fluid and returned to the reaction zone. The gas is fed into a gas cooler, in which it is cooled by cold solids. The solids consist on one hand of ash being cooled with the air prior to the air entering into the reaction zone and on the other hand of ash and carbonaceous residue filtered out of the reduced gas downstream the gas cooler. The latter solids are size-enlarged prior to their entering the gas cooler. <IMAGE>
