<p>Process for the continuous gasification of solids or liquids, contg. carbon and/or hydrocarbons, in a reactor contg. a bath of molten iron, the novelty being that the reactants, (a) the carbonaceous solids or liqs., and (b) oxygen or media contg. oxygen, are blown into the bath by one or more tuyeres located in the reactor below the free surface of the bath in a refractory lining and which therefore wear way at the same rate. Materials (a) are pref. coal and/or heavy oil, whereas material (b) is pref. oxygen, surrounded by a protective medium of, or contg., gaseous or liq. hydrocarbonds. The reactants are pref. fed simultaneously together with any finely-powdered slag-making materials via the tuyere(s), or they may be added separately. Used for prodn. of redn. gas fed to a blast furnace for mfg. crude iron from iron ore, where the use of the redn. gas results in a substantial saving of the amt. of coke required.</p> |
