Abstract
The invention relates to a hydrocarbon catalytic cracking method in the presence of a catalyst in fluidized phase, within a tubular type reactor (1) containing an injection area. According to the invention, a substantial part of the load to be cracked is introduced into the injection area using at least one means of injection (3) of such load against the flow, in relation to the direction of flow of the catalyst grains, and a substantial part of the load to be cracked is simultaneously introduced in the same area using at least one means of injection (2) of such load in direction of the flow in relation to the direction of flow of the catalyst grains.
