摘要(Abstract)：

以CO_2为主的温室气体排放所带来的生态、环境和社会问题正逐渐受到人们的重视。目前，以火电厂烟气为CO_2气源的固碳技术仍处于中试和工业化开发阶段，但针对固碳过程的碳减排效益尚未有标准化的方法学及核算方法。结合某电厂建设运行的国内首套“火电厂二氧化碳化学链矿化利用碳捕集、利用与封存（CCUS）技术研究与示范项目”的矿化固碳路线工业化实践，采用全生命周期（LCA）碳排放因子法对化学链矿化利用CCUS技术路径的碳减排效益进行核算及评估。该示范项目年处理CO_2量为1364.56t，能够实现708.12 t CO_2的净减排，净减排率达到52%；将示范项目年处理量放大到10万吨级规模，CO_2净减排率可提升至76%。研究方法具有广阔的碳减排应用前景，可为我国实现碳中和目标提供技术支持。
