减压渣油与催化裂化油浆混合脱沥青的研究

STUDIES ON CO-DEASPHALTING OF VACUUM RESIDUE WITH FCC SLURRY

研究了减压渣油（减渣）催化裂化油浆混合原料为进料的混合脱沥青过程对混合原料中油浆脱除多环芳烃的效果。结果表明，混合脱沥青过程脱除油浆中多环芳烃是可行的，可以达到在分离减渣中沥青的同时，也分离油浆中多环芳烃的目的。当混合脱沥青过程的总脱沥青油收率在４６．３％～６４．０％时，油浆自身的脱沥青油收率在５７％～８５％，而减渣自身的脱沥青油收率在３８％～６１％；混合脱沥青过程中，从油浆得到的脱沥青油与油浆单独脱沥青得到的脱沥青油，在收率相近时，质量也相近。

The co-deasphalting performance of vacuum residue with FCC slurry was studied.The experiment results showed that the selective separation of polynuclear aromatics from FCC slurry and deasphalting of vacuum residue can both be achieved in co-deasphalting process. It was found that the DAO yield of FCC slurry was higher than that of vacuum residue under normal operating conditions. The quality of the DAO obtained from FCC slurry in co-deasphalting was similar to that of the DAO obtained from FCC slurry deasphalting alone at approximate yields.
