Abstract
A process for thermally converting methane e.g., at 1,000.degree.-1,300.degree. C. into hydrocarbons with higher molecular weights, especially ethylene comprises circulating a gas containing methane in ceramic channels (11) grouped in rows which cover at least a part of the reactor (1) length, parallel to its axis. At the reaction temperature, the temperature variation is kept at less than 20.degree. C. The rows of channels form multiple plates (4) which are not adjacent to one another and which define tight spaces (17) in which are housed the electric heating (5, 22) means that heat the channel plates in a first zone (9) through successive, independent cross sections substantially perpendicular to the axis of the reactor and substantially parallel to the plane of the plates. Means for heating, servocontrol and modulation (7, 8) regulate the heating system. At the exit of the heating zone (9), the effluent is cooled in a second zone (10) equipped with cooling means and finally collected.
