ABSTRACT:
Process and device for the production of ethane and/or ethylene by heterogeneous catalytic reaction of methane and oxygen using a catalyst suitable for the formation of C.sub.2 hydrocarbons at increased temperatures, whereby in continuous operation a mixture of methane and oxygen is reacted at temperatures between 500.degree. and 900.degree. C. and at an oxygen partial pressure of less than 0.5 bar at the reactor entrance, while the ratio of the methane partial pressure to the oxygen partial pressure is greater than 1.
The conversion reaction takes place with or without gas recycling in a reactor containing a bed of solid catalyst or by the use of a fluidized bed of fluidized catalyst particles, or in a cross-flow reactor with distributed input of oxygen.
