【摘要】：針對S Zorb工藝生產(chǎn)清潔汽油過程中普遍存在產(chǎn)品汽油終餾點(diǎn)升高的問題,以催化裂化汽油和直餾汽油為原料,在小型固定床反應(yīng)器上考察了S Zorb吸附脫硫反應(yīng)前后汽油餾程、組成的變化。結(jié)果表明:經(jīng)S Zorb吸附脫硫后,產(chǎn)品汽油的終餾點(diǎn)隨反應(yīng)溫度的升高而上升;產(chǎn)品油重組分中芳烴含量普遍增加,導(dǎo)致烴類碳數(shù)增加的烯烴的存在以及高沸點(diǎn)芳烴含量增加是導(dǎo)致終餾點(diǎn)上升的重要因素;C5以下輕組分在S Zorb過程中主要發(fā)生加氫反應(yīng),不會生成芳烴。反應(yīng)過程中除發(fā)生加氫反應(yīng)外,還發(fā)生了鏈烷烴環(huán)化和環(huán)烷烴脫氫芳構(gòu)化反應(yīng),在實(shí)驗(yàn)室條件下,總體表現(xiàn)為碳?xì)淠柋茸兓淮蟆?br/>[Abstract]:In order to solve the problem of increasing the final distillation point of gasoline in the process of producing clean gasoline by S Zorb process, the gasoline distillation range before and after S Zorb adsorption desulfurization reaction was investigated in a small fixed bed reactor using FCC gasoline and straight run gasoline as raw materials. A change in composition. The results showed that after desulfurization with S Zorb, the final distillation point of gasoline increased with the increase of reaction temperature, and the aromatics content in the recombination fraction of product oil increased generally. The existence of alkenes and the increase of high boiling point aromatics are the important factors leading to the rise of final distillation point. The light components below C _ 5 mainly hydrogenate in S Zorb process and do not produce aromatics. In addition to the hydrogenation reaction, chain alkane cyclization and cycloalkane dehydroaromatization took place in the reaction process. Under the laboratory conditions, the total hydrocarbon molar ratio changed little.
