首次采用简单的共沉淀法合成了一种新型的氧化镁基多孔吸附剂，为高温下捕集烟气中的二氧化碳提供了候选材料。由于微晶氧化镁在氧化铝骨架中的均匀分散和分布，形成了类混凝土结构，因此复合材料具有介孔结构和较宽的孔径分布。这些吸附剂可以在高温(150-400摄氏度)下捕获二氧化碳，在循环吸附-解吸过程中具有高反应性和稳定性，为控制二氧化碳排放提供了有竞争力的候选者。(C)2011爱思唯尔B.V.保留所有权利。
A novel MgO-based porous adsorbent has been synthesized in a facile co-precipitation method for the first time, in order to provide a candidate for trapping CO2 in flue gas at high temperature. The resulting composite exhibits a mesoporous structure with a wide pore size distribution, due to the even dispersion and distribution of microcrystalline MgO in the framework of alumina to form a concrete-like structure. These sorbents can capture CO2 at high temperature (150-400 degrees C), possessing high reactivity and stability in cyclic adsorption-desorption processes, providing competitive candidates to control CO2 emission.
