| 为了有效应对全球气候变暖达到碳中和的目标，碳捕集、利用与封存(CCUS)技术被大力推广和应用。CCUS过程，油气开发和集输过程始终面临着严重的二氧化碳(CO2)腐蚀问题。CO2腐蚀会带来严重的经济损失、环境污染和人身安全等问题。相比于采用昂贵的合金材料防腐措施，在普通碳钢基础上添加缓蚀剂是应对CO2腐蚀较为简单、经济的防腐方法之一。总结了近几年不同类型CO2缓蚀剂的研究进展，包括传统的含有N、O、S、P等杂原子的有机缓蚀剂，含有杂环的有机缓蚀剂，具有两亲性的表面活性剂类缓蚀剂，新型无机纳米材料类缓蚀剂(如石墨烯、碳量子点、离子液体和金属配合物等)，以及植物提取物、氨基酸、天然油和生物聚合物等天然型绿色环保缓蚀剂。分析了这些不同缓蚀剂的优缺点和适用性，并讨论了这些缓蚀剂的研究现状。同时，总结了缓蚀剂构效关系和协同效应的研究热点及其存在的问题。最后针对这些不同缓蚀剂的特点和研究现状，对未来CO2缓蚀剂的研究方向进行了分析与展望。 |

| Carbon capture, utilization and storage (CCUS) technology has been widely applied in order to effectively deal with global warming and achieve the goal of carbon neutrality. CCUS processes, oil and gas development, gathering and transportation are always faced with serious carbon dioxide (CO2) corrosion problems. CO2 corrosion will bring serious economic losses, environmental pollution and personal safety problems. Compared with corrosion resistance alloys, addition of corrosion inhibitors to carbon steel is one of the most flexible, economical and easy to operate anti-corrosion methods to cope with CO2 corrosion. In this paper, the research progress of different types of carbon dioxide corrosion inhibitors was reviewed. CO2 corrosion inhibitors were classified according to organic and inorganic compounds. At present, organic corrosion inhibitors were widely used and mature in research. Firstly, the research progress of organic corrosion inhibitors containing heteroatoms such as N, O, S and P, organic corrosion inhibitors containing heterocyclic rings and amphiphilic surfactants were discussed. The advantages, disadvantages and applicability of these organic corrosion inhibitors were reviewed, and the current state of art in research of these inhibitors was discussed. Synthesis of organic compounds containing N, O, S, P heteroatoms and unsaturated bonds such as aromatic rings was the target and direction of the synthesis of CO2 organic corrosion inhibitors. Most efficient CO2 organic corrosion inhibitors were essentially surfactants. The amphiphilicity of surfactants was an advantage as corrosion inhibitors. However, these classical organic corrosion inhibitors were often toxic or useful in high doses. Green, non-toxic, environmental protection was also one of the indicators to measure the quality of corrosion inhibitors. Recently, some emerging inorganic materials began to be used as CO2 corrosion inhibitors. Then, some green inhibitors, such as new inorganic nanomaterial corrosion inhibitors (graphene, carbon quantum dots, ionic liquids and metal complexes), as well as plant extracts, amino acids, natural oils and biopolymers were discussed. Inorganic and nano materials were gradually used as CO2 corrosion inhibitors, which was a new direction of corrosion inhibitor research. The effect of plant extract as CO2 corrosion inhibitor was not good and still controversial. The existing single corrosion inhibitor often could not reach the ideal effect. Therefore, it was particularly important to study the structure-activity relationship of CO2 corrosion inhibitors and the synergistic compounding of CO2 corrosion inhibitors. The focus of the research on the structure-function relationship, synergistic effect of corrosion inhibitors and its existing problems were reviewed. A variety of polar groups provided more possibilities for the future study of the structure-activity relationship of CO2 corrosion inhibitors. The structure-activity relationship of a corrosion inhibitor or even a class of corrosion inhibitors needed further study. It was far from enough to only focus on the ratio and effectiveness of a single formula and the mechanism of macroscopic adsorption film level. The addition of quantum mechanical calculation and molecular dynamics simulation could better explore the mechanism of corrosion inhibitor collaborative adsorption and corrosion inhibition from the molecular, atomic or even electronic level. Finally, according to the characteristics and research status of these different corrosion inhibitors, the future research direction of CO2 corrosion inhibitors was summarized and proposed. |
