摘要
为了更有效地减少主要的温室气体CO2的排放量,在不添加额外的分离装置和消耗额外能源的情况下,急需找到一种可行的新型燃烧方式。基于零排放理念的化学链燃烧技术,它不仅能有效地富集高浓度的CO2,而且还将大幅提高能源的利用效率,实现多种污染物的协同控制。与煤焦反应时,铁基氧载体表现出高的反应程度,且尾气中CO浓度均较低,易于收集高浓度的CO2。这些都证实了煤基化学链燃烧技术的可行性以及其低排放特性。
Becanse the crisis caused by the global wanning has attracted more and more attention, a new combustion technology without special CO2 separation equipment and morn energy consumption is needed to reduce the CO2 emission effectively. The chemical looping combustion technology, which is based on the principle of zero emission, can not only enrich high CO2 concentration, but also increase the energy conversion efficiency and decrease the emission of various pollutants. In the char/air cycle reaction, Fe-based oxygen carriers have higher reaction conversion ratio and lower CO concentration in flue gas which is easier for the CO2 capture. All evidences above can testify the feasibility of chemical looping combustion of coal based and its lower emission characteristic.
