摘要： The disclosure relates to a process to perform a catalytic cracking reaction of hydrocarbons having at least four carbons, said process comprising the steps of providing a fluidized bed reactor comprising at least two electrodes and a bed comprising particles, wherein the particles are put in a fluidized state to obtain a fluidized bed; heating said bed to a temperature between 500° C. and 850° C. by passing an electric current through the fluidized bed to conduct the reaction. The process is remarkable in that the particles of the bed comprise electrically conductive particles and particles of a catalytic composition, wherein at least 10 wt. % of the particles are electrically conductive particles and have a resistivity from 0.001 to 500 Ohm.cm at 500° C. and in that the step of heating the fluidized bed is performed by passing an electric current through the fluidized bed.
