摘　　要：系统分析了国内外典型CCUS技术的研究进展,包括全氧燃烧、冷却氨吸收、膜分离及钙循环等技术,重点介绍了青州中联全氧燃烧耦合碳捕集示范项目的研究成果。青州中联示范项目通过全氧燃烧技术实现了水泥生产高效碳捕集,突破了高氧浓度燃烧火焰控制、CO_(2)富集浓度及高CO_(2)浓度条件下生料分解等关键技术难题,创新开发了分级供氧、离散稀释燃烧等方法,显著降低了碳捕集能耗和成本。研究表明,全氧燃烧技术可将烟气中的CO_(2)浓度提升至80%以上,为低能耗物理碳捕集奠定了基础。青州中联项目的成功运行,为水泥行业低碳技术的产业化应用提供了重要示范。This paper systematically analyzes the research progress of typical CCUS technologies worldwide,including oxy-fuel combustion,chilled ammonia absorption,membrane separation,calcium looping technologies,etc.It focuses on the research outcomes of the Qingzhou Zhonglian oxy-fuel combustion coupled carbon capture demonstration project.The Qingzhou Zhonglian demonstration project achieved efficient carbon capture in cement production through full oxy-fuel combustion technology,overcoming key technical challenges such as high-oxygen concentration flame control,CO_(2) enrichment concentration,and meal calcining rate under high CO_(2) concentration conditions,through innovative methods such as graded oxygen supply and discrete dilution combustion,the energy consumption and cost of carbon capture have been significantly reduced.The research indicates that oxy-fuel combustion technology can increase the CO_(2) concentration in flue gas to over 80%,laying a foundation for low-energy physical carbon capture.The successful operation of the Qingzhou Zhonglian demonstration project provides an important example for the industrial application of low-carbon technologies in the cement industry.
