| Research Abstract |
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.
