Iron sulfide-AC adsorbents were prepared and their mercury removal capabilities were evaluated in the simulated coal combustion flue gases. The FeS2has much higher mercury removal rate than AC although it has much lower BET surface area than AC. FeS2also shows higher mercury removal rate than FeS, which is probably due to its higher free sulfur content on the FeS2. The mercury removal capability of AC modified FeS2decreases with increasing of AC content. Temperature programmed desorption/decomposition process (TPDD) shows FeS and FeS2have more desorption peak than AC and the main peaks of FeS and FeS2are at around 240°C. The desorption peaks of AC modified FeS2are shifted to the higher temperature compared with that of FeS2and more mercury compositions are desorbed by AC modified FeS2.
