| 摘 要： | 为降低排放物中的芳烃含量（主要是苯、甲苯和二甲苯），开发出一种低温催化氧化工艺，该工艺以 O3为氧化剂，以自行制备的NiO/γ-Al2O3为催化剂，将芳烃转化为无毒的CO2和H2O,达到无污染排放。研究了不同负载金属、氧化镍含量、催化剂焙烧温度和反应时间等对芳烃氧化行为的影响。在反应温度60 ℃、负载氧化镍质量分数为15%、焙烧温度550 ℃和反应时间50 min时，芳烃的氧化效率可达到84%左右。

| Abstract: | A low temperature catalytic oxidation process was developed to reduce aromatics (mainly benzene, toluene and xylene) in the effluents. Aromatics were converted to harmless carbon dioxide and water over NiO/γ-Al2O3 catalyst with ozone as the oxidant.Influences of active metals,NiO loadings, calcination temperature and reaction time were investigated.Aromatics oxidation efficiency of about 84% was obtained under the following condition:reaction temperature 60 ℃,NiO loadings 15%（mass fraction）,calcination temperature 550 ℃ and reaction time 50 min. |

| Keywords: | aromatics ozone catalytic oxidation catalyst |
