In order to research and develop technologies that have China's independent intellectual property rights and cost-effective carbon dioxide (CO2) capture and storage, and promote CO2 emission reduction, the “Eleventh Five-Year†national science and technology support plan key project, CO2 capture and storage technology project, has begun to apply. The National “863†Plan Office of Resources, Environment and Technology issued a news report on February 28. The project will focus on the development of CO2 absorption, capture, adsorption, and storage technologies, focusing on the high energy consumption and high CO2 capture and storage. Cost issue.
It is understood that CO2 absorption capture technology mainly studies two parts. The first is the development of a new type of highly efficient absorption solvent. This project will adopt a combination of molecular modeling, molecular design, and experimental research for CO2 emission sources in coal-fired power plants and other industries to develop high-performance, low-energy, and low-corrosive chemical, physical, and chemically coupled absorption solvents. The exploratory study of new technologies such as sulfur and carbon integrated removal and membrane-absorption coupling was conducted. The second is the absorption of extra large equipment and process optimization. Combining advanced experimental measurement techniques, computational fluid dynamics simulations, and experimental methods, the authors will study ways of strengthening large-scale separation equipment, develop tower components such as high-efficiency absorption tower packing, and develop simulation optimization techniques for CO2 absorption and separation processes to study energy-saving The new process of consumption, and then the formation of absorption technology to capture CO2 integrated technology solutions and development platform.
CO2 adsorption capture technology mainly develops new high-efficiency adsorption materials and optimizes the adsorption and separation process. This project will develop new adsorption and separation materials with high selectivity, high adsorption capacity, and low desorption energy consumption. The research on optimization technology of adsorption and separation process focuses on optimizing the design of the process flow of CO2 adsorption and separation process, establishing laboratory scale and intermediate experimental devices, researching and determining the low operating energy consumption process parameters, and establishing a technical platform optimized from adsorbent development to adsorption tower design. , Forming an integrated new technology for the capture of CO2 by adsorption.
CO2 storage technology focuses on the urgent need for greenhouse gas CO2 emission reduction, and studies the CO2 storage technology of terrestrial or submarine geological saline aquifers. This topic will aim at the latest trends in foreign development, research and development of CO2 storage technology with independent intellectual property rights, advanced and practical. Through key technological breakthroughs, low-cost CO2 storage technology suitable for China's geological conditions has been developed.
