英文摘要：

Based on the proposed thermal cycle with inherent CO2 separation using methanol-chemical looping combustion by low-grade solar thermal energy, this paper discussed the principle of upgrading low-temperature solar thermal energy, and disclosed the relationships among the radiation intensity, the reactivity of CH3OH-Fe2O3, and the energy-level upgrade of solar thermal energy. The experimental study on the reaction of CH3OH-Fe2O3 was carried out by a thermogravimetric analyzer （TGA）. The Fe2O3 particles were prepared with impregnation techniques, and the surfaces configures of the particles before and after reaction were analyzed by the scanning electron microscope （SEM）. The promising results obtained here will provide the useful theory and experimental data for the energy conversion principle of the energy system integrating methanol-chemical looping combustion and low-temperature solar thermal energy.
