摘要利用修正的两段提升管催化裂化的三集总动力学模型分析了两段提升管催化裂化技术的动力学特点，并对中试装置的试验数据进行了拟合。
It is shown that the gam and alsphene in the seven catalytic stocks were not very high except in residual oil ; the saturate hydrocarbons in all seven were hig her ; aromatic contents were lower except in slurry oil and recycle oil , therefore , t he s even catalytic stocks except slurry oil and recycle oil are all good feedings of catalytic cracking unit
分析测定结果表明，这7种催化原料油除常渣外，胶质沥青质含量均不高；饱和烃含量均较高；芳烃含量除油浆、回炼油外，其余原料含量均较低，所以除油浆、回炼油外，均是作催化裂化的良好原料。
