PROCESS AND DEVICE FOR TREATING CATALYST DISCHARGED FROM BUBBLING BED HYDROGENATION OF RESIDUAL OIL Russian patent published in 2017 - IPC B01J38/02 B01J38/48 B01D43/00 B09B3/00 C10G53/02 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for treating a catalyst discharged from bubbling bed hydrogenation of residual oil. Method comprises following steps: (1) adjustment and control to reduce viscosity, wherein catalyst discharged intermittently from a bubbling bed hydrogenation reactor for residual oil, is adjusted for storage and then discharged continuously, subjected to temperature adjustment by adding water, such that viscosity of oil adsorbed on surfaces and inside pores of discharged catalyst particles is reduced, and flowability of adsorbed oil on surfaces and inside pores of the discharged catalyst particles is improved; (2) desorption and separation by rotational flow, wherein adsorbed oil is desorbed and separated from surfaces and inner pores of discharged catalyst particles by a flowing shear force from a rotational flow field; (3) separation and resource utilisation of three phase oil-water-catalyst, wherein oil/water/catalyst mixture produced from desorption and separation by rotational flow, is subjected to three-phase separation, achieving recovery of oil, recycling of water obtained by separation, and full recovery of solid particles obtained by separation. Invention also discloses a device for implementation of method.

EFFECT: technical result consists in reduction of cost of treatment, simplified process, higher oil recovery factor, reduced tendency to formation of secondary sources of contamination.
