Introduction Human-induced warming of the climate system has been accepted as one of the most important problems driving climate change and needs to be controlled. Most of the observed global warming over the last 50 years was likely caused by greenhouse gas forcing, with the dominant contributor being CO2. Fossil fuel combustion systems such as coal-fired power plants are consid ered to contribute 33-40% of all anthropogenic emissions of carbon worldwide [1] With the increasing growth in demand for electric power developing countries such as China have constructed new coal fired power plants to keep pace with economic development and demands. In China, coal is a much more abundant resource than other fossil fuels, such as oil and natural gas, so China chooses coal as the primary fuel for power production. Therefore, we must reduce the co2 emission of coal-fired power plants and try to maintain the position of coal as a viable energy option in a carbon-constrained world. There are several potential strategies to achieve this goal: (1) improving the efficiency of power plants; (2) introducing of combined cycles-as-fired or IGCC, which can ch high thermal efficiencies; (3) replacing hydrocarbon fuel with renewable resources; (4) capturing and storing CO2 from con entional plants [2]. Currently, capture and storage of CO2 has
