Abstract: This study focuses on the effect of temperature and time on the co-liquefaction of butadiene rubber and phenanthrene.GC,GC-MS and TG-DTG are utilized to characterize colloidal samples,phenanthrene and its co-liquefied products.The results identify that temperature has a great influence on the co-liquefaction and the yield of soluble substance remains constant at 96% with prolongation of reaction time.Analysis through GC shows that there are two functional groups of -CH3 and -CH2 in liquefaction fractured samples,but no shed -COOH functional groups.TG-DTG detection shows that excessive free radical fragments can be generated in unit time at over high temperature,which causes surplus free radical to condense into coke,resulting in the reduction of conversion rate.
