摘要： 固态有机胺二氧化碳吸附剂具有高选择性、低腐蚀性、易再生等特点,有着减少二氧化碳排放的潜在应用前景. 但是,如何在大量引入氨基的同时,保持氨基在载体上具有高分散度是制备固态胺吸附剂的难题. 本文综述了近年来固体胺二氧化碳吸附剂的研究进展,重点介绍开拓利用介孔分子筛原粉的分级结构,将有机胺涂布到介孔分子筛孔道中的丝状胶束以及胶束和硅壁之间的间隙中,可以显著地提高二氧化碳的吸附量.

Abstract: How to incorporate a large amount of amine onto a porous host material and how to keep the guest well dispersed and distributed are crucial for the developmen t of solid amine adsorbents. The progresses on the design and preparation of sol id amine adsorbents are reviewed. Originating from the specific interaction of t he template with amine, the resulting composites possess a high capacity for CO 2 adsorption.
