Abstract

PURPOSE: To produce a desulfurizing agent with a large power regardless of the type of material coal by raising the temperature at a smaller rate in the specified temperature area when producing desulfurizing agent for a dry type desulfurizing process by carbonizing coal.
CONSTITUTION: When producing desulfurizing agent for adsorbing and removing a sulfur oxide in an exhaust gas by carbonizing and activating coal, the temperature of the coal is raised in a carbonating furnace 42 by an exhaust gas from a burning furnace 68. At this point, the temperature is raised at a smaller tate in the temperature range of 350W550°C than in other ranges. Because no change takes place in the coal texture in the process in which tar component leaves, a strong desulfurizing agent can be obtained regardless of the type of material.
