Abstract: Introduces three different coupling forms of CO2 capture and transformation in situ coupling, CO2 capture and transformation alternative coupling, and CO2 capture and transformation series coupling, and elaborates on the characteristics of different types of CO2 capture and transformation integration technology. Carbon dioxide capture, utilization, and storage (CCS) technology is one of the important technical means to achieve the "carbon peak, carbon neutral" goal, but the current research on the CO2 capture process and the CO2 transformation utilization process is carried out independently. The intermediate links of CO2 compression, transportation, and storage require a lot of energy consumption, leading to a higher overall cost of CCS technology. The CO2 capture and transformation integration technology organically couples the CO2 capture process and the CO2 transformation utilization process together, thereby reducing the cost of the entire process of CO2 capture and utilization. Finally, the opportunities and challenges faced by the CO2 capture and transformation integration technology are analyzed, and the future research direction of coupling CO2 capture and CO2 transformation is prospected.

摘要： 介绍了CO2捕集与转化原位耦合、CO2捕集与转化替代耦合、CO2捕集与转化串联耦合3种不同的耦合形式，阐述了不同类型CO2捕集与转化一体化技术的特点。二氧化碳捕集、利用与封存（CCS）技术是实现“碳达峰、碳中和”目标的重要技术手段之一，但当前对于CO2捕集过程和CO2转化利用过程的研究是独立开展的，CO2压缩、运输、封存等中间环节需要消耗大量的能源，导致CCS技术整体成本较高。CO2捕集与转化一体化技术将CO2捕集过程和CO2转化利用过程有机耦合在一起，从而降低了CO2捕集利用全流程的成本。最后分析了CO2捕集与转化一体化技术目前面临的机遇和挑战，并对未来耦合CO2捕集与CO2转化的研究方向进行了展望。
