In this study, the HCl absorption performance in simulated coal gasification fuel gases of cheap natural soda ash loaded on a honeycomb support as a hot gas cleanup method is investigated by using flow-type fixed-bed reactor. The HCl removal performance of the honeycomb-supported soda ash at 500°C in 1000ppm HCl/12-28%H2/N2 reveals that H2 does not affect the HCl absorption ability. On the other hand, the coexistence of 26-58%CO to 1000ppm HCl/12-28%H2/N2 decreases the HCl removal performance by carbon deposition from disproportionation reaction of CO. However, the addition of 2-10%CO2 to 1000ppm HCl/12-28%H2/26-58%CO/N2 improves the HCl absorption ability. In addition, the HCl removal performance of the honeycomb-supported soda ash in HCl/12%H2/26%CO/6%CO2/N2 depends on the HCl concentration (500-2000ppm) and reaction temperature (300-600°C).
