Claim 18:
19. The process according to claim 1, characterized in that, the at least one fluidized bed reactor provided in step a) comprises a heating zone and a reaction zone, the fluid stream provided in step b) is provided to the heating zone and comprises diluent gases, and the step c) of heating the fluidized bed to a temperature ranging from 700° C. to 1000° C. to conduct the steam cracking reaction of a hydrocarbon feedstock comprises the following sub-steps:
heating the fluidized bed to a temperature ranging from 700° C. to 1000° C. by passing an electric current through the heating zone of the at least one fluidized bed,
transporting the heated particles from the heating zone to the reaction zone,
in the reaction zone, putting the heated particles in a fluidized state by passing upwardly through the said bed of the reaction zone a fluid stream comprising a hydrocarbon feedstock and optional diluent gases to obtain a fluidized bed and to conduct the steam cracking reaction on the hydrocarbon feedstock, and optionally
heating the fluidized bed to a temperature ranging from 700° C. to 1000° C. to conduct the steam cracking reaction of a hydrocarbon feedstock further comprises the sub-step of recovering the particles from the reaction zone and recycling them to the heating zone.
