近年來隨著環(huán)保要求日益嚴(yán)格,重質(zhì)油脫硫已成為一項(xiàng)迫在眉睫的任務(wù),研究開發(fā)新型的重質(zhì)原料油脫硫技術(shù)勢在必行。加氫脫硫是最傳統(tǒng)的石油餾分脫硫技術(shù),其能脫除大部分硫化物,但難以脫除噻吩類硫化物,而噻吩類硫化物卻是渣油中的主要硫化物。氧化脫硫（ODS）通常在常壓和中等溫度下進(jìn)行,且無需使用昂貴的氫氣。除此之外,ODS常用于脫除輕質(zhì)油品中難以脫除的噻吩硫。因此,本文利用噻吩類硫化物氧化后極性增加,提高其在極性溶劑中溶解度的原理,從而深度脫除重質(zhì)油品中的硫化物。首先用過氧化物氧化劑搭配催化劑對模型油中的二苯并噻吩（DBT）進(jìn)行氧化,選用乙腈作為萃取劑,利用紅外光譜、氣相色譜-質(zhì)譜聯(lián)用技術(shù)對反應(yīng)產(chǎn)物進(jìn)行分析,研究了氧化脫硫機(jī)理。然后使用減壓渣油進(jìn)行催化氧化萃取脫硫,考察了20O/S（摩爾比）、反應(yīng)時(shí)間、反應(yīng)溫度等工藝參數(shù)對氧化脫硫性能的影響。得到結(jié)論如下:1.以過氧化環(huán)己酮和MoO3為氧化劑/催化劑體系,考察不同反應(yīng)參數(shù):反應(yīng)溫度,反應(yīng)時(shí)間,催化劑用量和CYHPO/DBT摩爾比的影響。在120℃,反應(yīng)時(shí)間6小時(shí)和O/S比為2.0的優(yōu)化條件下,DBT的轉(zhuǎn)化率達(dá)到了2095.6%。2.使用過氧化羥基異丙...
