二氧化碳捕集技术进展研究

CO2排放主要源于化石燃料燃烧过程,减少化石燃料燃烧过程排放的CO2对于降低大气中CO2浓度具有重要意义.针对燃烧过程排放的CO2,分析了CO2捕集技术的原理、工艺流程、优劣性和适用性,并归纳了CO2捕集技术的研发趋势.结果表明:CO2捕集技术主要包括燃料燃烧前捕集、燃烧后捕集和富氧燃烧.为了有效缓解因CO2排放导致的一系列环境及社会问题,后续需要进一步降低CO2捕集技术的成本以及通过立法以约束企业的CO2排放行为.

Review on Progress of Carbon Dioxide Capture Technology

The fossil fuel combustion is the main source of carbon dioxide CO2 emissions.Thus, effective control of CO2 emissions from the fossil fuel combustion process is meaningful to mitigate CO2 concentration in the atmosphere.This paper presented the mechanism and schematic diagram of CO2 capture technologies for combustion process.The advantages, disadvantages, and application scope of these technologies were analyzed.The research trend of CO2 capture technologies was also provided.The results indicated that the CO2 capture processes could be divided into three main categories:post-combustion capture, pre-combustion capture and oxy-combustion process.In the future, both decreasing the cost of CO2 capture process and restraining the enterprises' CO2 emission behavior are acknowledged as two important ways to effectively mitigate a series of environmental and social problems due to CO2 emissions.
