碳捕获与封存技术综述

Overview of Carbon Capture and Storage Technology

人类活动排放的二氧化碳将导致全球温度上升,从而引发各种灾难。CCS是短期内减缓全球变暖速度的重要手段。文中综述了碳捕获和碳封存的技术方法,以及CCS技术存在的问题。碳捕获分为燃烧前捕获、富氧燃烧捕获和燃烧后捕获。碳封存方式有地址封存、洋封存、矿石碳化、工业利用、生态封存等,其中地质封存是主流方式。

Carbon dioxide emissions from human activities will cause global temperatures to rise, which cause all kinds of disasters. CCS is an important technology to slow down the speed of global warming. In this paper, we introduce some technology methods on carbon capture and sequestration, and some prob- lems about CCS technology. Carbon capture includes pre-combustion capture, capture and oxyfuel combus- tion capture. The ways of carbon sequestration include address sequestration, ocean storage, mineral carbonation, industrial use and storage of ecology, geological storage is a main approach.
