A comparative study of chemical looping combustion (CLC) with paper, plastic, and coal as fuel showed that higher temperature leads to an increase in CO2 yield and carbon conversion for all fuels. Paper had the highest CO to CO2 conversion followed by PVC and coal, attributed to the higher fraction of volatiles in paper. Scanning electron microscopy (SEM) analysis of the oxygen carrier particle showed slight differences in morphology after experiments with the three different fuels.
A comparative study of chemical looping combustion (CLC) with paper, plastic, and coal as fuel was carried out. Experiments were performed in a laboratory fluidized-bed reactor by alternating between reduction and oxidation cycles. The results obtained indicated that a higher temperature leads to an increase in the CO2 yield and carbon conversion for all fuels. Paper had the highest fractional conversion of CO to CO2 followed by polyvinyl chloride (PVC) and coal. This was due to the higher fraction of volatiles in paper compared to PVC and coal. Scanning electron microscopy (SEM) analysis of the oxygen carrier particle after each of the solid fuel experiment was carried out. For the used ilmenite, there was a slight difference in the morphology for the three different fuels.
