PROCESS OF PRODUCING CARBON AND HYDROGEN FROM HYDROCARBON GAS AND APPARATUS Russian patent published in 2008 - IPC C01B3/26 C01B31/02 

FIELD: petrochemical processes.

SUBSTANCE: invention relates to technology of processing hydrocarbon gas to produce pure carbon and hydrogen products. To that end, hydrocarbon gas is first preheated and then decomposed when affected by microwave electromagnetic field to isolate and separate carbon and hydrogen. Preheating of hydrocarbon gas is effected using energy of microwave electromagnetic field in thermal zone of elongated flow reactor uniformly filled with gas-permeable conducting substance serving as initiator and selected from titanium, nickel, titanium nickelide, aluminum nickelide, and molybdenum. Decomposition of hydrocarbon gas is effected at thermal zone outlet at elevated (as compared to thermal zone) intensity of microwave electromagnetic field. Apparatus comprises flow reactor with separately located hydrocarbon gas inlet and carbon/hydrogen outlet, and microwave emission source connected to microwave wave guide. Flow reactor is disposed within rectangularly-shaped microwave wave guide, said flow reactor being constructed itself as elongated cylindrical chamber made from radio-transparent heat-resistant material, partially filled with above-indicated initiator, and provided with microwave electromagnetic field concentrator disposed immediately behind initiator.

EFFECT: increased yield of desired products.
