摘要

二氧化碳已被发现是温室气体效应的主要人为贡献者，因此，发展碳捕获与封存(CCS)技术迫在眉睫。本文采用两种Al2O3柱状蒙脱土，一种zro2柱状蒙脱土和一种TiO2?+?制备了SiO2柱型蒙脱土，并利用x射线衍射(XRD)对其相形成进行了表征，利用N2吸附-脱附等温线对其表面积和孔径分布进行了表征。在273 K时测定了CO2气体的平衡吸附。柱状粘土对CO2的吸附能力随着孔隙体积的增大而增大。柱状黏土对CO2的吸收量在0.53 ~ 1.18 mmol/g之间。

CO2 Adsorption by Several Types of Pillared Montmorillonite Clays

CO₂ has been found to be the main anthropogenic contributor to the greenhouse gas effect, thus, the development of carbon capture and storage (CCS) technology is extremely urgent. In this work, two kinds of Al₂O₃ pillared montmorillonite, one ZrO₂-pillared montmorillonite and one TiO₂?+?SiO₂ pillared montmorillonite were prepared and characterized by X-ray diffraction (XRD) for phase formation and N₂ adsorption–desorption isotherms for surface area and pore-size distribution. Equilibrium adsorption of CO₂ gas was measured at 273?K. CO₂ adsorption capacities of pillared clays increased with the increase of their pore volume. The uptakes of CO₂ by pillared clays were in the range of 0.53–1.18?mmol/g.
