Abstract
The fraction compositions, group compositions and structure compositions of seven catalytic stocks were determined by means of vacuum distillation, ma ss spectrum, element analysis and molecular mass measurement. The effects o f the compositions of different catalytic stocks on catalytic cracking reac tions were discussed. It is shown that tae gum and asphaltene in the seven catalytic stocks were not very high except residual oil; The saturated hydr ocarbon in the seven were all higher; Aromatic contents were lower except s lurry oil and recycle oil, therefore, the seven catalytic stocks except slu rry oil and recycle oil are all good feedings to catalytic cracking unit. T he results also show Liaohe oil turns heavier from low sulphur middle-paraf fin base to low sulphur naphthene-middle base.
