Results showed that single ozone oxidation can only remove about 50% nitrobenzol, single active carbon absorption can reduce nitrobenzol to a standard index mark when empty-bed station time exceeded 15 minutes, but ozone oxidation-active carbon absorption technology can remove nitrobenzol completely when the time exceeded 10 minutes.

研究發(fā)現(xiàn)：單獨采用0 氧化能去除約50％的硝基苯；單獨采用活性炭吸附操h网站，在空床停留時間大于15 min時可使出水指標達到標準要求99在线视频精品；而對于O 氧化一活性炭吸附工藝，當停留時間在10 min 以上時射射射操操操，可完全去除水中的硝基苯。

The experiment results show that the yield of hexane catalyzed by the nano-fibrous catalyst was 4.7 times higher than that of PdCl_2/γ-Al_2O_3 catalyst. The hydrogenation ofα-tetradecylene, cyclohexene, nitrobenzol and styrene by the nano-fibrous catalyst was also studied, the selectivity to primary products of the hydrogenation of cyclohexene, nitrobenzol and styrene was 100%.
