Abstract
A desulfurization system removes sulfur ingredients included in synthetic gas generated from gasification of coal in a high temperature dry state. The system includes a desulfurization reactor, a desulfurization cyclone, and first and second regeneration reactors branched with the desulfurization cyclone. A first oxidizing agent is injected to a first oxidizing agent inlet of the first regeneration reactor, and a second oxidizing agent is injected to a second oxidizing agent inlet of the second regeneration reactor. A controller operates one of the first and second regeneration reactors in a regeneration mode, controlling the other to operate in a desulfurization mode.
