摘要：AbstractChemical-looping Combustion (CLC) has recently emerged as a promising technology to curb CO2emissions. The novelty of CLC resides on its inherent ability of avoid direct contact between the fuel and the air, while producing a highly concentrated CO2stream. This study presents a dynamic modelling and controllability study that demonstrates the technical feasibility of a fixed bed CLC reactor to produce a constant high temperature air stream during the oxidation stage. The heterogeneous model, which considers mass and heat transport resistances in the oxygen carrier particle and the bulk fluid phase, was validated using data reported in the literature. Also, a sensitivity analysis was conducted to gain insight on system’s behaviour. Furthermore, an optimal control problem was formulated to identify optimal control profiles that can improve the efficiency of this process.
