摘　　要：高温环烷酸腐蚀是世界炼油工业的宿敌,也是目前亟待解决的难题之一。由于环烷酸腐蚀的影响因素十分复杂,许多问题至今还没有形成统一的认识。综述和探讨了环烷酸腐蚀机理及其影响因素的研究进展,探讨了存在的问题和可能的重点研究方向,提出了高酸油炼制和预测其腐蚀时的一些建议,以期为高酸原油加工时的腐蚀与防护提供理论参考。Naphthenic acid corrosion at high temperature has been an old enemy in oil refining industry, and also one of the problems desiderate to be solved. Many problems are still not completely understood because of the complex influencing factors. An overview and discussions of the mechanism of naphthenic acid corrosion and its controlling factors have been undertaken. Existing problems and the possible research emphases in the future are discussed. Some advices on high acid value crude oil processing and the prediction of its corrosion have been given. This paper hopes to give theoretic references for the corrosion and protection when high acid value crude oil processed.
