Process to conduct an endothermic catalytic cracking reaction in a fluidized bed reactor

A process to perform an endothermic catalytic cracking of one or more hydrocarbons having at least four carbons, said process comprising the steps of:

• a) providing at least one fluidized bed reactor comprising at least two electrodes and a bed comprising particles;
• b) putting the particles of the bed in a fluidized state by passing upwardly through the said bed a fluid stream, to obtain a fluidized bed;
• c) heating the fluidized bed to a temperature ranging from 500° C. to 850° C. to conduct the endothermic catalytic cracking reaction of one or more hydrocarbons having at least four carbons;
• d) optionally recovering the cracking products of the reaction;
• the process is characterized in that the particles of the bed comprise electrically conductive particles and particles of a catalytic composition, wherein the catalytic composition comprises from 5.0 to 90.0 wt. % of one or more zeolites comprising at least one 10-membered ring channel and based on the total weight of the catalyst composition;
• wherein at least 10 wt. % of the particles based on the total weight of the particles of the bed are electrically conductive particles and have a resistivity ranging from 0.001 Ohm.cm to 500 Ohm.cm at 500° C.;
• wherein the void fraction of the bed is ranging from 0.5 to 0.8;
• and in that the step (c) of heating the fluidized bed is performed by passing an electric current through the fluidized bed.
