Generally, amine group captures CO2 according to 2:1 or 1:1 stoichiometry. Here, we report a kind of improved carbon capture using amino‐functionalized ionic liquids (ILs) through 1:2 stoichiometry. A serial of amino‐functionalized ILs various with basicity and steric hindrance of anion were designed, prepared, and applied in CO2 capture. Through a combination of absorption experiment, quantum chemical...
Pulverized coal-fired (PC) power plants are the major technology used to generate electricity for power generation around the world. These processes are generally considered to make a significant contribution to global climate change since they have high CO 2 emissions, with the exception of those coal-fired power plants that employ CO 2 capture and storage (CCS) technology.With regard...
Global concentration of CO 2 in the atmosphere is increasing rapidly. CO 2 emissions have an impact on global climate change. Effective CO 2 emission abatement strategies such as Carbon Capture and Storage (CCS) are required to combat this trend. There are three major approaches for CCS: post-combustion capture, pre-combustion capture and oxyfuel process. Post-combustion capture...
Post-combustion capture by chemical absorption using MEA solvent remains the only commercial technology for large scale CO 2 capture for coal-fired power plants. This paper presents a study of the dynamic responses of a post-combustion CO 2 capture plant by modelling and simulation. Such a plant consists mainly of the absorber (where CO 2 is chemically absorbed) and the regenerator...
Power generation from fossil fuel-fired power plants is the largest single source of CO 2 emissions. Post combustion capture via chemical absorption is viewed as the most mature CO 2 capture technique. This paper presents a study of the post combustion CO 2 capture with monoethanolamine (MEA) based on dynamic modelling of the process. The aims of the project were to compare...
