Abstract
The disclosure relates to a process to perform an endothermic methane pyrolysis reaction, said process comprising the steps of providing at least one fluidized bed reactor comprising at least two electrodes; and a bed comprising particles, wherein the particles are put in a fluidized state by passing upwardly through the said bed a fluid stream, to obtain a fluidized bed; heating the fluidized bed to a temperature ranging from 500° C. to 1200° C. to conduct the endothermic methane pyrolysis reaction; wherein 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 ranging from 0.001 Ohm·cm to 500 Ohm·cm at 800° C. and wherein the step of heating the fluidized bed is performed by passing an electric current through the fluidized bed.
