锆基金属有机骨架同系物的合成及合成气中CO2吸附与分离研究

synthese of Zr(Ⅳ)metal-organic framework analogues for CO2 adsorption and separation in syngas

中文摘要英文摘要

二氧化碳的吸附和分离在减少温室气体排放、提高能源利用率、促进空气分离等方面具有重要意义。金属有机骨架材料(Metal-Organic Frameworks, 简称MOFs),是一种由金属离子和有机配体自组装形成的新型多孔配位聚合物。因其高的比表面积、孔径大小和结构可调及孔壁可修饰等优点,在气体吸附和分离方面具有巨大的应用潜力。本文选取了UiO-66和功能化的UiO-66-Cl2为研究对象,开展了对其合成气中CO2、CO、H2的吸附性能研究,且通过Langmuir模型计算了CO2/CO分离因子。结果表明:功能化后的UiO-66-Cl2对合成气中CO2的分离性能显著提升。

arbon dioxide capture and separation is an important industrial process. Metal-organic Framewroks (MOFs) are a new class of porous materials composed of metal-cluster units together with organic ligands by covalent bonds. Their many unique properties such as super-high surface area, tunable pore structures and functionalized pore walls make them great potential in terms of gas adsorption and separation. In this article, we selected UiO-66 and functionalized UiO-66-Cl2 as the candidates for CO2 separation from syngas. These materials were synthesized and characterized by PXRD, TGA, BET and gas adsorption to analysis the CO2 separation performance. Meanwile, separation factor of CO2/CO was calculated by Langmuir model.The results show that CO2 separation performance of the functionalized UiO-66-Cl2 is significantly increased.
