【摘要】 化石燃料的燃烧是人类排放CO2的主要来源。对近几年新兴的CO2减排及利用技术进行了总结和分析,并重点介绍了一种新型CO2减排技术——基于循环载氧体的化学链燃烧技术。化学连燃烧通过不同品位能的梯级利用,具有比传统燃烧方式更高的能源利用效率,而且在CO2富集、污染物协同控制方面具有优越性。更多还原

【Abstract】 Fossil fuel consumption is the major source of anthropogenic CO2 emission.Some new CO2 emission reduction and utilization technology are summerized and analyzed in the paper.Chemical looping combustion based on circulating oxygen carriers is especially introduced as a new-style CO2 emission reduction technology.Chemical looping combustion involves the cascade utilization of chemical energy,which has high thermal energy conversion in comparison with traditional thermal cycles.Moreover,it has more superiority in CO2 enrichment and synergistic effects of contamination control.更多还原
