Description

technical field [0001] The invention belongs to the fields of petrochemical industry and environmental protection, and relates to a method and a device for oil recovery, water circulation, and catalyst particle reduction and recovery after hydrothermal desorption of a fluidized bed residue oil hydrogenation exhaust catalyst. Specifically, the present invention relates to a post-treatment method and device for hydrothermal desorption of an ebullated-bed residual oil hydrogenation exhaust catalyst. Background technique [0002] The ebullated bed residual oil hydrogenation exhaust catalyst is a mixture of catalyst particles and oil, and the oil phase can be desorbed and separated from the surface of the exhaust catalyst particles and the internal pores by using a hydrothermal desorption method. [0003] Hydrothermal desorption method, also known as hot water washing method, can be used for deoiling oily solid waste. In the specific implementation process of treatment, it is re...
