Abstract

<PICT:0801090/III/1> In the treatment of hydrocarbon oils with hydrogen using a molybdenum catalyst, the catalyst is regenerated in situ by (1) discontinuing the oil feed to the reactor 18 or 19 requiring reactivation, and continuing the hydrogen feed to the catalyst bed, e.g. 20, to remove liquid hydrocarbons; (2) then admitting steam from a furnace 47 through a manifold 51 and pipe 38 to the top of the bed; (3) the temperature of the steam feed is increased to about 850 DEG F. and air is admitted through line 46 which in admixture with the steam is fed into the catalyst bed 18, whereby carbonaceous deposits are burned off, the temperature not exceeding about 1000 DEG F.; (4) at the end of this stage air feed is increased for a short time and then discontinued, while steam treatment continues; (5) the catalyst is finally reactivated by admitting hydrogen or recycle gas through a supply pipe 60. The hydrogen and petroleum vapours formed in the first stage are separated in a unit 27. The regeneration cycle takes about 24 hours and may be applied to molybdenum catalysts supported on alumina, and consisting of molybdenum trioxide or sulphide, or cobalt molybdate.
