Abstract
The present invention describes a reaction zone comprising at least two fluidized reactors, a principal reactor for cracking a heavy hydrocarbon cut, the other, additional, reactor for cracking one or more light cuts, the effluents from the two reactors being treated in a common gas-solid separation and quench zone. Performance is enhanced because the thermal degradation reactions in the reaction zone are controlled in an optimum manner.
