[ What is claimed is:] [1.] A hydrocarbon catalytic cracking method in the presence of a catalyst in a fluidized phase, in a tubular reactor whose flow is essentially upward (1) or downward (41), and having an injection area for a first and a second load to be cracked, said method comprising the steps of:a) injecting a substantial portion of the first load into the injection area against the flow in relation to the direction of flow of catalyst grains, andb) simultaneously, injecting a substantial portion of the second load into the same injection area in the same direction of flow in relation to the flow of the catalyst grains;wherein, said first and second loads are the same or different.
