变温镁基 CO2吸附剂的制备及应用 I. Na/Mg 物质的量比
Preparation and application of magnesium-based CO2 sorbent for temperature swing absorption I. Na/Mg mol ratio
摘要
Abstract
A series of magnesium-based CO2 absorbents with different Na/Mg molar ratios were prepared by precipitation method with Mg ( NO3 ) 2 and Na2 CO3 as raw materials, and characterized by various methods ( including XRD, SEM-EDS and DTG) to study the compositions, morphology and decomposition temperature and so on. The CO2 absorption performance was evaluated by temperature swing absorption-desorption dynamiccyclic tests to check the impact of Na/Mg molar ratio. It can be seen that optimum molecular ratio of Na to Mg is 8 . 15 , and the sorbents is homogeneous with lower decomposition temperature caused by small particles of the sample, and initial CO2 adsorption capacity can reach 9. 584%. Good recycling capability can be obtained aswell. Compared with the initial absorption capacity there was only . % decrease after recycles.关键词
