催化裂化油浆糠醛分离及应用

为了增加催化裂化(FCC)装置的处理量,提高轻质油的收率,需要大量的外甩油浆。而大量的FCC油浆外甩导致部分可裂化的烷烃、芳烃等理想组分进入油浆,从而造成FCC原料的损失。目前FCC油浆除作为燃料油外,只是部分作为其他装置的调和组分,利用率较低。为了充分合理的利用油浆,采用糠醛分离油浆的方法,可以有效地将油浆的可裂化组分与稠环芳烃分离。实验结果表明,油浆中可裂化组分可以作为催化裂化或加氢裂化原料;富含芳烃的馏分可以用于生产增塑剂、软化剂、沥青等化工产品,具有良好的应用前景。

Separation of Catalytic Cracking Slurry Oil With Furfural and Application

In order to increase the processing quantity of the catalytic cracking unit and the recovery of its light oil, it is necessary to discharge the slurry oil largely. This makes part of alkane and aromatics, which are the ideal components for the refinery, into the slurry oil causing the FCC feedstock loss. At present, the discharged slurry oil is partly used as the blending component for other units besides as the fuel oil, so, it is under utilized. To lift the reasonable utilization of it, furfural extraction was used to separate the slurry oil, this method can effectively separate the cracking part and the faction containing mass aromatics in slurry. The results show: the cracking part of the slurry can be used as catalytic cracking feedstock or hydrocracking feedstock; the faction containing mass aromatics can be applied to produce such chemicals as plasticizing agent, softening agent, asphalt, and so on. Its application is an optimistic one.
