摘要： A hydrodemetalation catalyst of a hydrocarbon oil comprising a support and a catalyst component supported by the support, and provided on a part of a catalyst surface with a coating layer made of an inactive material not substantially having a demetalation function and not substantially permeating a reaction fluid. Preferably, this catalyst has a reaction flow path inside the catalyst through which a reaction fluid flows, and is preferably having a cylindrical or honeycomb structure having a single or a plurality of through-holes. In a hydrodemetalation treatment of heavy oils using such a hydrodemetalation catalyst of a hydrocarbon oil, fixation of catalysts can be prevented, a rapid rise of differential pressures can be prevented by keeping spaces between the catalysts, and a continuous operation can be carried out for a long time.

摘要： A hydrodemetallizing catalyst for a hydrocarbon oil comprising a support and a catalytic component carried on the support, this catalyst having a surface, part of which has a coating layer composed of an inert substance having substantially no demetallizing activity, this coating layer allowing substantially no reaction fluid to permeate therethrough. This catalyst preferably has a reaction flow path through which a reaction fluid flows thereinside and is preferred to be, for example, in the form of a honeycomb structure or cylinder having one or a plurality of through holes.
In the hydrodemetallization of heavy oils using the above hydrodemetallizing catalyst for a hydrocarbon oil, the sticking of the catalyst can be prevented and the spacing between catalyst particles can be maintained to thereby prevent a rapid increase of differential pressure, so that a continuous operation can be performed for a prolonged period of time.
