Abstract: Amine molecule plays a role of improving selectivity on the CO2 capture. Small size ethylenediamine molecules were selected to modify the light metal Al-based metal-organic framework (MOFs) MIL-100Al with unsaturated metal sites in this work, the structure of the materials was characterized by XRD, N2 adsorption and FT-IR. The adsorption properties of MIL-100Al modified with different concentrations of ethylenediamine on CO2 and CH4 were tested. Compared with the original MIL-100Al sample, the amount of CO2 adsorbed by MIL-100Al modified with ethylenediamine is significantly improved, while CH4 adsorption decreases. The CO2/CH4 adsorption selectivity of the material therefor is further improved, and the performance of adsorption separation is enhanced. |
