Research progress on CO2 capture and separation technology
The huge emission of greenhouse gas CO2 is one of the main reasons for global warming.CO2 capture,utilization and storage(CCUS)technology is the only way to achieve near zero CO2 emissions in the large-scale utilization of fossil fuels in the future.The research and application status of carbon dioxide capture before combustion,post-combustion carbon dioxide capture of flue gas and carbon dioxide capture technologies during combustion(oxygen enriched combustion and chemical looping combustion)was elaborated.The research progress on CO2 separation technologies such as absorption,adsorption and membrane separation was also summarized.And it was pointed out that the focus in the future should be on enhancing the research on high-value CO2 gas utilization technologies to reduce the high cost of CCUS,while actively developing efficient and energy-saving CO2 capture technologies.
