Intensification Insights from Chemical Looping Combustion Using Coal−Biomass Mixtures with Fe-Based Oxygen Carrier

Chemical looping combustion (CLC) is a modern technology that enables the mitigation of the CO2 concentration without any expense of energy. Experimental evidence shows that combustion of coal/biomass in CLC technology leads to negative carbon emission by replacing the portion of coal with biomass. In the present work, CLC was simulated using a mixture of coal/biomass in CLC; using their different proportions resulted in enhanced CO and CO2 fractions in the fuel reactor. The carbon capture and oxide oxygen fraction were also found to increase with the enhancement of the fuel reactor’s temperature with different proportions of coal/biomass. Increases in the carbon capture efficiency and oxide oxygen fraction of up to 98.86% and ~98%, respectively, were observed within the experimental temperature range. The simulated results of various parameters were predicted and validated with the published experimental results. The stated parameters were also predicted as a function of the different rates of solid circulation and gasification agents. Higher coal char conversion was confirmed in the fuel reactor with the presence of higher biomass concentrations.
