METHOD AND PROCESS FOR CONVERTING THE ETHYLENE PRESENT IN THE OVERHEAD EFFLUENT FROM A FCC IN A MANNER SUCH AS TO INCREASE THE PROPYLENE PRODUCTION

The present invention describes a process for fractionating the gaseous fraction leaving overhead from the fractionation column of a catalytic cracking unit (FCC) using a unit for the conversion of ethylene into propylene, in order to upgrade the ethylene contained in the fuel gas.
