The book 'CO2 Sequestration Technologies for Clean Energy' is about management of CO2 by capturing and fixing it away from the atmosphere for clean energy development. Energy industry is the target industry for adoption of CCS in fossil fuel based economies. In a coal based power plant CO2 can be captured at various stages of pre-combustion, during combustion and post combustion. Research work being carried out on mixed metal oxides as CO2 absorbents for pre-combustion capture and pressure swing adsorption techniques for CO2 post combustion capture are discussed in two different chapters....
