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.

温室气体减排是一个重要而又复杂的问题。为了在这一领域取得突破，开发一种新的低能耗甚至零能耗的CO_2捕集技术是非常重要的。为了实现这一目标，我们提出了一种新型的燃气涡轮机动力装置。该系统中的化学链燃烧室由燃料反应器（燃料与金属氧化物反应）和空气反应器（金属与空气中的氧气反应）组成。这种新系统不需要额外的CO_2分离能量消耗（即，无能耗损失，无CO_2分离设备。因为CO_2是通过冷凝燃料反应器出口气体中的水蒸气而获得的。通过对该系统的研究，我们发现了该系统的突破点，并获得了新的实验结果，有效回收CO_2和无NOx生成，同时具有较高的能量效率，表明这种新型化学链燃烧器可能成为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，并为这一突破性概念在温室气体控制中的应用开辟了广阔的前景。
