ABSTRACT:
The invention concerns a method of catalytic reforming in a plurality of fluidized bed type reaction zones located side by side, the catalyst circulating from zone to zone with the aid of elevating means and a carrier gas in the form of hydrogen. According to the invention, nitrogen is used as the elevating gas to raise the exhausted catalyst drawn off from the bottom of the last catalytic zone (through which the feedstock passes) to the top of the catalyst regenerating zone, and also to raise the regenerated catalyst to the top of the first catalytic zone through which the feedstock passes.
