制药行业有机废气催化燃烧研究进展

Research progress in catalytic combustion of organic waste gas in pharmaceutical industry

制药行业在我国快速发展,带来经济增长与生活便利的同时也带来了大量挥发性有机污染物(VOCs)的排放。针对制药行业废气排放量大、排放节点多、污染物种类复杂等特点,催化燃烧因经济环保、应用灵活,成为处理制药VOCs的合适选择。本文总结了制药行业排放的典型VOCs及常见医用药品生产过程中的特征污染物,并着重从催化燃烧催化材料研发及应用的角度,总结了近年来制药行业典型VOCs催化燃烧技术的研究现状,同时对我国制药行业有机废气治理作了展望,即需进一步加深制药行业VOCs排放特征、VOCs实验室治理等基础研究来保证实际治理过程中的经济有效性;同时在原有催化氧化催化剂研究的基础上,研发多技术耦合工艺,实现制药行业废气的达标排放。

The rapid development of the pharmaceutical industry in China brought economic growth and convenience to life,as well as large volatile organic pollutants(VOCs)emission.Among various VOCs purification methods,catalytic combustion is considered as a good one with favorable environmental friendliness and flexibility for purifying pharmaceutical VOCs which is characterized by the large emission,multiple emission nodes,and complex types of pollutants.In this paper,typical volatile organic compounds emitted from the pharmaceutical industry and the characteristics of these pollutants were summarized.Based on this,the development and application of catalytic materials in the catalytic combustion of pharmaceutical VOCs in recent years were further summarized.Meanwhile,the prospect of organic waste gas treatment in China’s pharmaceutical industry was proposed.Firstly,more in-depth researches such as pharmaceutical VOCs emission characterization and laboratory scale VOCs purification should be performed to ensure the economic effectiveness in the actual purification process.Secondly,new process coupling multi-technology should be developed to improve the purification efficiency to meet the pharmaceutical industry exhaust emission standards in China.
