Claim 0:
1. A process to perform an endothermic catalytic cracking of one or more hydrocarbons having at least four carbons, comprising:
a) providing at least one fluidized bed reactor comprising at least two electrodes and a bed comprising particles, wherein:
i) the particles of the bed comprise electrically conductive particles and particles of a catalytic composition;
ii) the catalytic composition comprises from 5.0 to 90.0 wt. % of one or more zeolites based on the total weight of the catalyst composition, the zeolite comprises at least one 10-membered ring channel;
iii) 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.; and
iv) a void fraction of the bed ranges from 0.5 to 0.8;

b) injecting a fluid stream upwardly through the bed to putting the particles of the bed in a fluidized state thereby obtaining a fluidized bed;
c) heating the fluidized bed to a temperature ranging from 500° C. to 850° C. by passing an electric current through the fluidized bed and cracking the hydrocarbons by endothermic catalytic cracking reaction; and
d) optionally recovering the cracking products of the reaction.
