Abstract

Separation of carbon dioxide (CO(2)) from gaseous mixture is an important issue for the removal of CO(2) in natural gas processing and power plants. The ordered mesoporous silicas (OMS) with uniform pore structure and high density of silanol groups, have attracted the interest of researchers for separation of carbon dioxide (CO(2)) using adsorption process. These mesoporous silicas after functionalization with amino groups have been studied for the removal of CO(2). The potential of functionalized ordered mesoporous silica membrane for separation of CO(2) is also recognized. The present paper reviews the synthesis of mesoporous silicas and important issues related to the development of mesoporous silicas. Recent studies on the CO(2) separation using ordered mesoporous silicas (OMS) as adsorbent and membrane are highlighted. The future prospectives of mesoporous silica membrane for CO(2) adsorption and separation are also presented and discussed.

摘要

从气体混合物中分离二氧化碳（CO2）是天然气处理和发电厂去除 CO2 的重要问题。具有均匀孔结构和高密度硅醇基团的有序介孔硅（OMS）引起了研究人员的兴趣，用于通过吸附过程分离二氧化碳（CO2）。这些经过氨基官能化的介孔硅已被研究用于去除 CO2。功能化有序介孔硅膜在 CO2 分离中的潜力也得到了认可。本文综述了介孔硅的合成以及与介孔硅开发相关的重要问题。重点介绍了最近使用有序介孔硅（OMS）作为吸附剂和膜分离 CO2 的研究。还提出并讨论了介孔硅膜在 CO2 吸附和分离方面的未来前景。
