采用燃烧催化剂和臭氧作为氧化剂的耦合技术，对几种挥发性有机化合物（VOC），如卤代和非卤代脂肪族和芳香族分子进行完全燃烧。以臭氧代替氧气作为氧化剂，催化燃烧温度降低，能耗显著降低。VOC以低浓度（空气中≤ 2000 ppm）作为纯化合物以及混合物进料。在选定的催化剂上，钡促进的氧化铝负载的铜-铬氧化物（Ba-CuO-Cr_2O_3/Al_2O_3），几种化合物的燃烧进行了比较研究与无臭氧。验证了不完全燃烧危险产物（PIC）的形成。通过XPS分析对新鲜形式和使用后的催化剂进行表面表征，以找出结构-活性关系。
A coupled technique utilizing a combustion catalyst and ozone as oxidant was used to perform the complete combustion of several volatile organic compounds (VOC), such as halogenated and non-halogenated aliphatic and aromatic molecules. The decrease of the catalytic combustion temperature when using ozone as oxidant instead of oxygen, led to a remarkable reduction of energy consumption. VOCs were fed at low concentration (≤ 2000 ppm in air) as pure compounds as well as in mixtures. On the selected catalyst, barium promoted copper-chromite oxide supported on alumina (Ba-CuO-Cr2O3/Al2O3), a comparative study of the combustion of several compounds with and without ozone was performed. The formation of hazardous products of incomplete combustion (PIC) was verified. Surface characterization by XPS analysis of the catalyst in fresh form and after use was performed in order to find out structure-activity relationships.
