PROCESS AND DEVICE FOR TREATING CATALYST DISCHARGED FROM HYDROGENATION OF BUBBLING BED RESIDUAL OIL

摘要

Provided is a process for treating a catalyst discharged from the hydrogenation of a bubbling bed residual oil the method comprising the following steps: (1) adjustment and control to reduce the viscosity wherein the catalyst discharged intermittently from a reactor for the hydrogenation of a bubbling bed residual oil is adjusted for storage and then discharged continuously subjected to temperature adjustment by adding water such that the viscosity of the oil adsorbed on the surfaces and inside the pores of the discharged catalyst particles is reduced and the flowability of the oil adsorbed on the surfaces and inside the pores of the discharged catalyst particles is improved; (2) desorption and separation by rotational flow wherein the adsorbed oil is desorbed and separated from the surfaces and the inside pores of the discharged catalyst particles by a flowing shear force from a rotational flow field; and (3) separation and resource utilization of the three phase oil water catalyst wherein the oil/water/catalyst mixture produced from the desorption and separation by rotational flow is subjected to a three phase separation achieving the recovery of the oil the recycling of the water obtained by separation and full recovery of the solid particles obtained by separation. Also provided is a device for treating a catalyst discharged from the hydrogenation of a bubbling bed residual oil and the use of this device in the treatment of oil containing solid waste.
