Abstract
The present invention relates to a device and to a process for the fluidized bed catalytic cracking of a hydrocarbon feedstock, in which: a first feedstock () is cracked in a dense fluidized bed reactor () in the presence of a catalyst () to produce a first effluent; and at least one second feedstock () is cracked in a transport fluidized bed reactor () in the presence of the catalyst () supplied by the dense fluidized bed reactor () to produce a second effluent, the second feedstock () being a heavier feedstock than the first feedstock ().
