Surface Modification Of Activated Carbon In The Synthesis Of Ethylene Glycol Reaction

Applied Study on the Superficial Transformation of Active Carbon in the Hydration of Ethylene Oxide to Ethylene Glycol ABSTRACT In this paper , the superficial transformation of active carbon , the sulfonated petroleum coke is firstly used to synthesize ethylene glycol (EG) by hydration of ethylene oxide (EO) , and the catalysis of sulfonated petroleum coke (SPC) is studied. The results indicate that SPE has high activity and good selectivity of EG in hydration reaction of EO . And sulfonation temperature has a certain effect on the activity of SPC , the higher the temperature , the feebler the activity , thus when petroleum coke is sulfonated in low temperature , its activity will be better than in high temperature ; Moreover, alone with the sulfonation temperature ascending , the number of acid-site of SPC gradually increase , but the activity wears off, it also shows that weak acid catalyst is more sutible for hydration reaction of EO ; In addition, the effect of reactive temperature on the activity of SPC is greatest, when reactive temperature going up , the activity of SPC is speedily enhanced , but when temperature exceeds a certain range, the activity of SPC will reduce ; And the activity of SPC will become stronger alone with reactive pressure rising , but when pressure exceeds a certain value , selectivity of EG will decrease Also , increasing airspeed will weaken the activity of SPC. Abstract At the same time , through investigating the catalysis of woodiness active carbon , the results show that it also has good activity in the hydration reaction of EO to EG , but that awaits for further studying.
