摘要:

近年来,餐饮油烟逐渐成为城市大气污染的主要来源之一,油烟中挥发性有机化合物(VOCs)对人体及环境均产生非常大的危害,对其治理刻不容缓。催化燃烧技术因具备去除效率高、无二次污染等优点在有机废气治理方面有着广阔的应用前景。鉴于此,本文首先总结并分析了油烟中典型挥发性有机物的成分,发现油烟中烃类、醛酮类污染物含量较高,其次包括酸酯类、醇类和少量的多环芳烃类污染物。在此基础上,重点综述了催化燃烧技术对净化上述典型挥发性有机污染物的研究进展,并对近年来常用的催化剂包括贵金属催化剂、非贵金属催化剂及特定结构的催化剂进行了归纳和整理。最后结合油烟VOCs成分及其特点,总结了不同种类型的催化剂在油烟治理中的适用性,并对催化燃烧技术在油烟治理方面的研究前景作出了展望。

Abstract:

In recent years, cooking oil fumes (COFs) have gradually become a major source of air pollution in cities. Volatile organic compounds (VOCs) in cooking oil fumes do great harm to both human body and environment, which need to be purified as much as possible. Catalytic combustion is an efficient and widely used technology for removing various organic compounds due to its high removal efficiency as well as environment friendliness. In this paper, the compositions of typical volatile organic compounds in COFs were firstly summarized and analyzed based recent researches. It was found that hydrocarbons, aldehydes and ketones are the major components in COFs, followed by esters, alcohols and a small amount of polycyclic aromatic hydrocarbons. Then, the research development on the catalytic oxidation of these typical VOCs in COFs was reviewed systemically. Particularly, the catalysts commonly used for the catalytic combustion, including precious metal catalysts, non-precious metal catalysts and catalysts with specific structure, were summarized. Finally, the feasibility of different types of catalysts for purifying the VOCs from COFs was analyzed based on the review above. Moreover, the application of catalytic combustion technology in the treatment of COFs was prospected.

Key words: cooking oil fumes (COFs), catalytic oxidation, hydrocarbon, aldehyde ketone, ester, volatile organic compounds (VOCs)
