摘要:

CO₂是造成温室效应的最主要气体,本文综述了燃烧后捕集、富氧燃烧捕集及燃烧前捕集三种 CO₂回收技术的发展及应用情况;鉴于燃煤烟气中 CO₂分压低,适宜采用化学吸收法捕集 CO₂ ,重点介绍了氨水、有机胺、热钾碱、强碱等化学吸收剂捕集 CO₂的机理及应用。

关键词：燃煤 CO₂ 捕集 有机胺；

Abstract：

CO₂ is the main greenhouse gas. In this paper, the development and application of three CO₂ recovery technologies including post-combustion capture, oxygen-enriched combustion capture and pre-combustion capture are reviewed; in view of the low partial pressure of CO₂ in the flue gas from coal combustion, it is suitable to use chemical absorption method to collect CO₂ , the mechanism and application of chemical absorbers such as ammonia water, organic amine, hot potassium alkali and strong alkali to capture CO₂ are introduced.
