Diffusion in Porous Solids: Insights into the Effect of Pore Structure

该项目将通过使用零长度柱（ZLC）和吸附差容仪（ADVA）测量单个商业珠子、颗粒和成型材料的质量传输和吸附来解决这一空白，这些分子包括Ar、N2、CO2、正烷烃和甲苯。然后将在FIB-FEM设备中对相同的珠子进行测试，以获得纳米尺度上的详细结构信息。该项目的主要成果将是建立一个大型的结构和质量传输信息数据库，这将形成验证先进的多尺度建模方法的基础，以预测多孔材料中的扩散。

This project will address this gap by measuring mass transport and adsorption on individual commercial beads, pellets and formed materials using the zero length column (ZLC) and the adsorption differential volumetric apparatus (ADVA) with a range of molecules (including Ar, N2, CO2, n-alkanes and toluene). The same beads will be then tested in the FIB-FEM facility to obtain detailed structural information at the nanoscale. The main outcome of the project will be a large database of structural and mass transport information on the same individual beads, which will form the basis for validating advanced multiscale modelling approaches to predict diffusion in porous materials.
