METHOD FOR CARRYING OUT THE REACTION OF AN OXYGEN-CONTAINING REGENERATED CATALYST BEFORE ITS USE IN A REACTOR WITH A FLUIDIZED BED Russian patent published in 2021 - IPC C10G11/18 C07C5/333 B01J38/34 

FIELD: chemical technologies.

SUBSTANCE: method for carrying out the reaction of a stream of an oxygen-containing regenerated catalyst before its use in a fluidized bed reactor is proposed, including: regenerating a stream of a spent catalyst to obtain a stream of a regenerated catalyst, that contains a regenerated catalyst and at least 0.001 wt % oxygen relative to the total weight of the regenerated catalyst stream; bringing the stream of the regenerated catalyst into contact with a fuel source at a temperature of at least 400°C and for a reaction time of 0.1 to 60 seconds, which results in the formation of oxides and a decrease in the oxygen content in the stream of the regenerated catalyst, to obtain a stream of a regenerated catalyst with minimized oxygen content; and feeding a regenerated catalyst stream with a minimized oxygen content to a fluidized bed reactor containing a hydrocarbon.

EFFECT: minimizing the amount of oxygen entering the fluidized bed reactor along with the regenerated catalyst.
