Sažetak
The intensifying effect of metallic iron on the gasification process is realized through two possible mechanisms. According to one of them, iron accelerates the last stage of the carbon gasifi cation process - the release of CO due to the destruction of keto complexes. According to another mechanism, the oxidation of iron with carbon dioxide leads to the formation of iron-oxygen complexes on the surface of the metal phase, the concentration of which is not the same. The presence of a concentration gradient leads to the migration of oxygen atoms along the iron surface to carbon grains, and partially penetrate into the interbasis spaces of its lattice. Probably, the influence of metallic iron is realized along both paths simultaneously.
