一段話翻譯成英語,催化脫硫方面
|
|
| 對于催化氧化活性較好的仲鎢酸鹽X,我們還考察了其循環(huán)利用效果和對真品柴油的脫硫能力。實驗結(jié)果顯示:催化劑重復(fù)利用五次后,催化活性未出現(xiàn)明顯下降,二苯并噻吩的轉(zhuǎn)化率可達到95.3%,且使用前后催化劑的化學(xué)結(jié)構(gòu)未發(fā)生明顯變化;催化劑對不同成分,不同硫含量的真品柴油都有很好的氧化脫硫能力,一次氧化-萃取過程后,柴油中的硫含量均降至50μg/g以下。 |

might be good ref. for you. As for the paratungstate X which has better catalytic oxidation activity, we also investigated its performances on recycling and desulfurization capability of genuine diesel. The experimental results show that: 1) There is no apparent decrease of the catalytic activity after re-use of the catalyst 5 times, and the dibenzothiophene conversion rate can reach to 95.3% without significant changes of the catalyst's chemical structure . 2) The catalyst shows excellent oxidative desulfuriztion performances on the genuine diesels with different compositions and Sulfur contents, and the sulfur content in the diesel can be reduced to below 50μg/g after one oxidation-extraction process. |
