Abstract:
A method of regenerating particulate catalyst used in a slurry reactor for the processing of a synthesis gas, the reactor containing a slurry containing a liquid, suspended finely-divided particulate catalyst and finely dispersed gas bubbles, the method comprising:a) flowing a slurry of partially deactivated particulate catalyst from the reactor to a selected one of a first regeneration vessel or a second regeneration vessel;b) regenerating the partially deactivated catalyst slurry flowed to the selected one of the first or second regeneration vessels to produce a regenerated catalyst slurry;c) returning the regenerated catalyst slurry from the selected one of the first or second regeneration vessels to the reactor; andd) simultaneously with the return of the regenerated catalyst slurry to the reactor, withdrawing a substantially equivalent volume of partially deactivated catalyst slurry from the reactor into the other of the first or second regeneration vessels.
