The pollution by cooking oil fumes is harmful to both environment and human body. This paper reviewed and summarized the main purification methods of cooking oil fumes in China in recent years as well as their individual features. Compared with other treatment technologies, catalytic combustion is green and of high efficiency which can purify a variety of organic waste gases. So, it has become an important research direction of cooking oil fumes treatment technology. In this paper, the recent research progress in cooking oil fumes purification by catalytic combustion technology was summarized. The recent progress of noble metal and metal oxides catalysts used in catalytic combustion technology were also reviewed. In addition, this paper expounded the deactivation and regeneration of the catalysts. Finally, regarding the existing problems, we put forward the prospect of the catalytic combustion technology and pointed out that the development of new catalyst is the key to this technology.
