【正文】 脫除油品中的硫化物 ， 是保證國內(nèi)煉油業(yè)與歐美等發(fā)達國家相比具有競爭力的基礎(chǔ) [1]。 汽油中的含硫化合物在燃燒后會生成硫氧化物 SOX, 其中最主要的是二氧化 硫 。隨著原油硫含量的增加以及汽油指標的嚴格 , 汽油脫硫顯得越來越重要。生產(chǎn)滿足環(huán)保要求的清潔燃料是全球煉油行業(yè)生產(chǎn)發(fā)展的總趨勢，隨著全球性原油變重、變劣及汽油硫指標的嚴格，汽油脫硫越來越重要。 adsorption ； catalysis oxidative desulfurization； 1 引 言 進入 21世紀，汽車污染日益成為全球性問題。 關(guān)鍵詞 ： 催化劑 ； 叔丁基過氧化氫 ； 吸附 ；催化氧化脫硫 II Catalytic Oxidative Desulfurization of Gasoline by TiPW Abstract： Dibenzothiophene (DBT) was selected to represent the anosulfur pounds in fuel oil, and in the deep desulfurization experiments, the solution of DBT dissolved in petroleum ether was used to model the fuel oil containing anosulfur pounds. The TiPW/SA was synthsized by solgel as catalyticsorbent and the 70%(w)aqueous solution of tertbutyl hydroperoxide was used as oxidant. The effects of the dosage of catalyst and oxidant and reaction temperature and reaction time on the desulfurization rate were investigated through orthogonal table L16 (44). The experimental results did not receive the expected results, the analysis results of main causes of the failure of the experiment from two aspects of catalyst and subsequent evaporation of gasoline the fuel oil desulfurization accumulated certain experience.
