Development of High-performance Chemical-looping Combustion

减少温室气体排放至关重要，但也是一个复杂而困难的问题。为了在这一领域取得突破，开发一种新的二氧化碳捕集技术具有重要意义，该技术的能量损失较小，甚至没有损失。为了实现这一目标，我们提出了一种新型的燃气轮机发电厂。该系统中的化学环燃烧器由燃料反应器(燃料反应器与金属氧化物反应)和空气反应器(金属与空气中的氧气反应)组成。该系统不需要额外的CO_2分离能耗(即没有能量损失)，也不需要CO_2分离设备。因为二氧化碳是通过冷凝燃料反应堆出口气体中的水蒸气而获得的。我们发现了该系统的突破点，并获得了新的实验结果。高效回收CO_2和NO_x生成的良好结果表明，这种新型的化学环燃烧器可能会带来一种同时缓解温室气体影响和提高能源效率的新技术。实验结果为实际反应器的设计提供了有价值的数据，并为将这一突破性概念应用于温室气体控制开辟了广阔的前景。

Greenhouse gas abatement is crucial but a complicated and difficult problem. To make a breakthrough in this field, it is important to develop a new technology for CO_2 capture with less or even no energy penalty. To achieve the objective, we have proposed a novel gas turbine power plant. The chemical-looping combustor in the proposed system consists of a fuel reactor (ftuel reacts with metal oxide) and an air reactor (the metal reacts witlt oxygen in air). This new system requires no additional energy consumption for CO_2 separation (i.e., no energy penalty) and no equipment for CO_2 separation. Because CO_2 is obtained by condensing water vapor in the outlet gas from the fuel reactor. We identified the breakthrough points in the proposed system and have obtained new experimental results.The promising results of effective recovery of CO_2 and no NO_x formation with high-energy efficiency indicated that this novel chemical-looping combustor might lead to a new technology for simultaneous mitigation of greenhouse gas impact and improvement of energy efficiency. The experimental results have provided the valuable data on design of a practical reactor and opened up broad prospects for applying this breakthrough concept to controlling greenhouse gas.
