S Zorb Catalytic Gasoline Adsorption Desulfurization Technology For Industrial Applications

In2013China will implement gasoline State IV emission standard, so how toimprove the quality of gasoline, reducing sulfur content in gasoline in refinery ismajor problem currently. S Zorb adsorption desulfurization technology for Gasolineis based on adsorption principle for desulfurization by adsorption, and adsorptsselectively the sulfur atom of sulfur-containing compounds to desulphury, is themost promising technology to achieve zero sulfur desulfurization targets currently.Thesis using a large number of production operation data, analyses the S Zorbgasoline adsorption desulfurization technology for industrial application, it isconcluded that the technology has high desulfurization rate (sulfur can be decreasedto10μg/g), octane number loss is small, the operating cost is low advantage; Thesisdiscusses the problems existing in industrial application: material/reaction heatexchanger fouling, the reactor cross tube feeding difficultly, regenerator, sorbentagglomerates filter reverse blow valve leakage, lock hopper pipeline blockage.Through theoretical and experimental analysis, thesis put forward a series ofimprovement measures such as stabilize gasoline directly flowing into the S Zorbdevice, the reactor put at the lower part, regeneration air dryer upgrade, lock hopperadopting auxiliary fluidized measures; combining with the design of1500000tons/year S Zorb device in Luoyang petrifaction, thesis put forward the devices for thedesign, and improvement and development suggestions of the S Zorb adsorptiondesulfurization technology are put forward.
