A process and a device for thermal conversion of methane into hydrocarbons of higher molecular weight. It comprises a reactor 1 of elongate shape, made of a refractory material, connected on the one hand, at a first end, to means for feeding 5 a gaseous mixture and, on the other hand, at the opposite end, to means of evacuation 10, the said reactor comprising on a first part (first end side) a plurality of electrical heating means 3 surrounded in a leakproof manner by ceramic sheaths 4. These means, substantially parallel to each other, are arranged in sheets which are substantially parallel to each other and perpendicular to the axis of symmetry of the reactor so as to define between the sheaths spaces or passages for the movement of the gaseous mixtures and/or of the effluents and are adapted to heat the said passages by means of independent successive cross-sections which are substantially perpendicular to the axis of the reactor. The reactor further comprises, on a second part 8 (opposite end side) which adjoins the first part, means for cooling 9 the effluents, connected to the means for feeding a coolant fluid. <IMAGE>
