摘要
Ru/AC催化剂催化臭氧氧化邻苯二甲酸二甲脂的实验结果表明:投加活性炭上负载Ru的催化剂可以显著提高臭氧氧化的效果,反应60min后,单纯由于Ru/AC催化臭氧氧化导致的TOC的去除率高达39%。实验还考察了制备条件对催化剂活性的影响并确定了催化臭氧氧化的最佳反应条件。在实验考查范围内:当焙烧温度为500℃,Ru的负载量为2.5%时催化剂活性最高;催化臭氧氧化最佳反应条件为:催化剂投加量为2g/L;气体流速为300mL/min;臭氧投加量为100mg/h。
With dimethyl phthalate as the model pollutant and Ruthenium as the catalyst,the catalytic ozonation degradation of TOC is systemically investigated. Results show that Ruthenium supported on activated carbon can significantly increase the effect of ozonation,and TOC removal resulting from Ru/AC catalytic ozonation only after 60 min reaction can reach 39% . Ruthenium activiness is upmost under the following conditions:calcination temperature,500℃;Ruthenium loading,2.5%. The optimal reaction condition of catalytic ozonation is:catalyst dosage,2g/L;gas flow rate,300mL/min;ozone dosage,100mg/h.
