【摘要】：在傳統(tǒng)催化汽油加氫脫硫催化劑基礎上,以γ-Al_2O_3為載體,Co-Mo-Ni為活性組元,采用等體積浸漬方法制備了一種催化汽油深度加氫脫硫催化劑。研究了現(xiàn)有技術生產國Ⅴ汽油存在的問題,考察了載體、活性組元、金屬負載量對催化劑催化性能的影響,并對催化劑穩(wěn)定性進行了研究。結果表明:該催化劑對硫含量滿足國Ⅳ標準(S≤50μg/g)的催化汽油產品進一步接力脫硫時,可脫除硫醇硫及其他形態(tài)硫,烯烴基本不飽和,加氫脫硫選擇性高達90%以上。該催化劑作為國Ⅳ升級到國Ⅴ標準的重要技術,降低了現(xiàn)有國Ⅴ技術的辛烷值損失,技術經(jīng)濟性更好。
[Abstract]:Based on the traditional catalytic gasoline hydrodesulfurization catalyst, using 緯 -Al _ 2O _ 3 as carrier and Co-Mo-Ni as active component, a catalytic gasoline deep hydrodesulfurization catalyst was prepared by iso-volume impregnation method. The effects of support, active component and metal loading on the catalytic performance of the catalyst were investigated. The stability of the catalyst is also studied. The results show that the catalyst can remove thiol sulfur and other sulfur forms when the sulfur content meets the national 鈪，
