摘要
A process for treating carbon-containing material contaminated with toxic elements utilises smelting of the material in a top-submerged lancing reactor. The material has its carbon content present as elemental or free carbon. Smelting is conducted so as to form, or in the presence of, a fluid slag. In the course of smelting, free-oxygen-containing gas is injected into the slag by top-submerged injection, to combust the carbon content of the material. Volatilizable toxic elements are discharged in reactor off-gas, while non-volatilizable elements are substantially fully incorporated into the slag.
