Process to conduct an alkane transformation into olefins in an electrified fluidized bed reactor

Abstract

The disclosure concerns a process to perform a reaction of alkane transformation into olefins, said process comprising the steps of (a) providing a stream of light alkane-comprising feedstock with one or more alkanes and one or more oxidants selected from COand/or COS; and 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 to obtain a fluidized bed; and (c) heating the fluidized bed to a temperature ranging from 600° C. to 1500° C. to conduct the reaction; the process is remarkable in that the step c) is performed by passing an electric current through the fluidized bed; the particles of the bed comprise electrically conductive particles, and in that, at least 10 wt. % of the particles are electrically conductive particles and have a resistivity ranging from 0.001 to 500 Ohm·cm at 800° C.
