β¦ Synopsis
Shengli residue was separated into several fractions by using alumina column chromatography and supercritical fluid separation. The various fractions, and the residue itself, were decomposed in a quartz boat heated by a tubular heater. The products of thermal conversion (volatiles, benzene-solubles and benzene-insolubles)
were recovered, and the variation of these product yields with time and temperature was investigated.
The data show that most of the benzene-insolubles came from the thermal conversion of the resins, and only an insignificant amount was obtained from the aromatics. In the present study, the relation between product yields of thermal conversion of the residue and its fractions was investigated, and the thermal conversion of the resin fractions of different molecular weight was also discussed.
