中文摘要：

本文提出一种新颖的甲醇化学链燃烧动力循环系统。该系统利用空气压缩的间冷热提供甲醇和Fe2O3反应热,将间冷的低温热转换为高品位化学能;同时得到预冷的空气吸收燃烧产物Fe2O3的显热,降低了还原反应的温度。与常规化学链循环相比,该循环利用间冷的热量代替高温Fe2O3的显热提供还原反应的反应热,系统内能量品位匹配更加合理。根据图像媚分析方法,阐明了甲醇化学链燃烧过程（火用）损失减少和间冷热品位提升的机理。本文对新循环进行了分析,并以常规化学链循环为参照,研究了其性能。新循环的效率较高,同时可以实现CO2无能耗的分离。

英文摘要：

Chemical-Looping Combustion is a process where the C02 can be captured with a zero energy penalty. A novel methanol based power system with chemical-looping combustion is proposed in this paper. The low-temperature intercooling energy is absorbed by reductive reaction in this energy system. This process upgrades the intercooling energy level. On the basis of system integration of cascade utilization of chemical energy of methanol and thermal energy, the thermal efficiency of this novel cycle is expected to be 58%, much higher than the Chemical-Looping Combustion system without intercooling, while the CO2 can be captured.
