摘　　要：大规模二氧化碳(CO_(2))排放会造成一系列环境与气候问题。钙基吸附剂由于成本低、理论吸附容量大,成为最具潜力的规模化烟气CO_(2)脱除手段之一。然而,钙基吸附剂存在高温烧结导致CO_(2)吸附能力逐渐衰减的技术瓶颈。因此,提升钙基吸附剂的抗烧结性能成为研究热点。该文总结钙基吸附剂的高温烧结机理,综述基于惰性载体提升钙基吸附剂抗烧结性能方法的研究现状。根据载体前体物与钙基吸附剂是否发生反应,将惰性载体分为双金属氧化物和单一相金属氧化物两类,重点介绍Ca-Al混合氧化物、CaZrO3和MgO等3种典型载体对钙基吸附剂抗烧结性能提升的作用机制。最后,对惰性载体强化钙基吸附剂脱碳性能的研究进行展望。Large-scale CO_(2)emissions will give rise to a range of environmental and climate issues.Calcium-based sorbents have emerged as one of the most promising methods for large-scale CO_(2)removal due to their cost-effectiveness and high theoretical adsorption capacity.However,the CO_(2)adsorption capacity of calcium-based sorbents is susceptible to deterioration caused by sintering at high temperatures.Therefore,the sintering mechanism of calcium-based sorbents at high temperature is summarized,and the research status regarding inert support that can enhance the sintering resistance of calcium-based sorbents is reviewed.Depending on whether metal oxides react with calcium oxide or not,inert supports are divided into bimetallic oxides and single-phase metal oxides.The mechanism of improving the anti-sintering properties of calcium-based sorbents by three typical supports such as Ca-Al mixed oxide,CaZrO3 and MgO is emphasized.Finally,prospects and suggestions for enhancing decarbonization efficiency through incorporating inert support in calcium-based sorbents are proposed.
