摘要

主要研究了活性炭催化过氧化氢氧化脱附其表面吸附的二苯并噻吩。比较了使用H2O2水溶液，H2O2+HCOOH水溶液和H2O2+CH3COOH水溶液对活性炭进行催化氧化再生的性能，并考察了催化条件对活性炭再生性能的影响。结果表明：3种不同的催化氧化再生方法都能使活性炭获得不同程度的再生，其中，使用H2O2+HCOOH水溶液进行催化氧化再生的活性炭再生效果最好，达90％以上。使用H2O2+HCOOH水溶液对活性炭进行再生时，H2O2浓度、HCOOH浓度、反应温度和时间对活性炭再生性能均有影响，选择合适的催化条件，可使再生性能达到最佳。

Abstract

The oxidative removal of dibenzothiophene adsorbed on activated carbon surface by hydrogen peroxide catalyzed by activated carbon itself was investigated.The regeneration performance of catalytic oxidation on the activated carbon by H2O2 solution，H2O2+HCOOH solution and H2O2+CH3COOH solution was compared firstly.Then the effect of catalysis condition on the activated carbon regeneration performance was studied.The results showed that all three catalytic oxidation methods could regenerate the used activated carbon to some extent.The regeneration performance was the best，reaching above 90% by using H2O2+HCOOH solution.H2O2 concentration，HCOOH concentration，reaction temperature and time affected the regeneration performance of activated carbon when using H2O2+HCOOH solution.The catalysis condition could be optimized to get high regeneration performance.
