Abstract
The invention relates to a process and a device for treating a catalyst discharged from bubbling bed hydrogenation of residual oil. Provided is a process for treating a catalyst discharged from bubbling bed hydrogenation of residual oil, comprising the following steps: (1) adjustment and control to reduce viscosity; (2) desorption and separation by rotational flow; and (3) separation and resource utilization of an oil-water-catalyst three phase. Also provided is a device for treating a catalyst discharged from bubbling bed hydrogenation of residual oil.
