A Review of the Research into Carbon Capture and Sequestration Technologies for Power Plants

One of the important missions for global carbon dioxide reduction is controlling the carbon dioxide emissions from power plants.Carbon capture and storage,a hot spot of the research among carbon dioxide reduction technologies,include physical adsorption/absorption,chemical absorption,physico-chemical absorption, membrane technology,biotechnology,and etc.,of which physical adsorption/absorption and chemical absorption are the main ones for carbon capture in power plants.To develop highly selective and efficient absorbents and capture processes,to improve energy efficiency,and to rationally arrange flue gas decarbonisation facilities are the challenges of carbon capture technologies for power plants.
