TY  - JOUR
AB - Pressurized chemical-looping combustion combined cycle (PCLC) system is proposed for processing coal with high system efficiency and low CO2 sequestration cost. In this work, PCLC of coal was carried out in a laboratory scale fluidized bed reactor to study the cyclic performance of CVRD iron ore oxygen carries with Xuzhou bituminous coal. Experiment results show that more pyrolysis gas is oxidized by the oxygen carrier with the redox cycles going on. The carbon conversion maintains approximately the same with the cycle numbers increasing. The oxygen carrier and carbon conversions increase with the reaction pressure increasing. X-ray diffraction (XRD) analysis indicates that the extent of reduction level increases with the cycle numbers and pressures. No detectable formation of compound of iron oxide and coal ash is observed. Scanning electron microscope analyses (SEM) show that the oxygen carries become porous. Agglomeration of particles is not observed in all experiments. The experimental results indicate that the iron-based oxygen carrier can be used in PCLC applications.
