Abstract
For commercialization of the fixed bed desulfurization system used for the integrated coal gasification combined cycle power generation, required is long-term stabilization of performance of desulfurizing agent. Since iron oxide based honeycomb desulfurizing agent is used repeatedly in this system, the system conducts removal of sulfur in coal gas (desulfurization), discharge of sulfur in desulfurizing agent (regeneration) and then preparation of desulfurization (reduction). In a test on repeated use of desulfurizing agent carried out under practical operation condition (pressurizing), stabilization of the performance is demonstrated and also a relation between absorbed sulfur and sulfur undischarged by regeneration and reduction (residual sulfur) is examined. Variations of the performance of desulfurizing agent are studied by changes of sulfur compound concentration (breakthrough curves) at the outlet at the time of desulfurizing. Breakthrough curves show almost the same curves on or after 10 cycles of repetition and the performance becomes stabilized. It is found that absorbed sulfur is influenced only by the residual sulfur after the performance is stabilized. 6 refs., 10 figs., 3 tabs.
