Abstract

A process for desulfurization of gases with molten mineral baths during gasification of carbon products comprises the replacement of limestone or calcomagnesium materials by metallurgical slags, such as blast-furnace or steel-furnace slags, having a high basicity index. By means of this replacement, substantial savings in material and energy are achieved. Moreover, the use of residual slags for production of mineral materials that can be granulated and pelletized having good hydraulic properties, and pig iron that can be reused in metallurgical circuits, is assured.
