ABSTRACT:
A process for the gasification of sewage sludge or other carbon-containing waste materials in a gasifier (1) is described. A solid fuel and oxygen-containing gas are also fed into said gasifier. The residues formed during gasification collect at the bottom of the gasifier in the form of molten slag. Gasification takes place in a fluidized bed (9) formed above the slag bath and constituted by the dried sewage sludge or waste materials, the solid fuel, the oxygen-containing gas and the gasification gas. The gas produced in the gasifier can be used for power generation or as a reducing gas for iron ore. Sponge iron can simultaneously be melted in the gasifier and reduced to pig iron.
