Paper Title
Chemical Looping Combustion of Charcoal with Calcium Modified Iron-Based Oxygen Carriers for Reduce Emission of Air Pollutants NOx and SO2

Abstract
Chemical looping combustion was conducted in a moving bed reactor with two kinds of an iron source as a reactive phase in oxygen carriers and modification with Ca(OH)2 was used to enhance reactivity with fuels. In the moving bed reactor, calcium modified electric arc furnace slag (EAF-slag)/Al2O3 and calcium modified iron oxide powder (Fe2O3)/Al2O3 were selected as oxygen carriers. The air pollutant analysis indicated that the emission of NOx and SO2 were very low for both Ca-modified iron-based oxygen carriers, which implies that the chemical looping combustion process could reduce emission of air pollutants.
