METHOD OF PRODUCTION OF SYNTHESIS-GAS AT COMBUSTION AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2008 - IPC C01B3/36 B01J7/00 

FIELD: processing of hydrocarbon raw materials; oxidizing conversion of hydrocarbon gases into synthesis-gas.

SUBSTANCE: proposed method is carried out in flow-through two-chamber reactor in turbulent mode at combustion of mixture of hydrocarbon raw material and oxidizer. Superheated water steam is additionally introduced into said mixture in the amount of 5-20 mass-% relative to mass of carbon fed in form of hydrocarbon raw material. Three-component mixture is ignited in combustion chamber by jet of hot gas fed from external source where pressure exceeds pressure in first chamber during ignition. Combustion products from first chamber of reactor are directed to second chamber via nozzle at critical difference in pressure and combustion process is continued till content of oxygen in combustion products does not exceed 0.3 vol-%. Process is carried out in combustion reactor which is made in form of two coaxial cylindrical chambers with cooled nozzle located in between them; section of this nozzle ensures required pressure differential between chambers. Injector unit mounted at inlet of first chamber is used for delivery of working mixture components. Turbulator is mounted in first chamber. Lateral surface of first chamber has one or several holes for introducing the jet of hot gas from external source whose pressure exceeds pressure of first chamber and volume of second chamber exceeds that of first chamber. Proposed method makes it possible to produce synthesis-gas at H₂/CO ratio approximately equal to 2.0; residual content of oxygen does not exceed 0.3 vol-% and content of carbon black does not exceed trace amount.

EFFECT: enhanced efficiency.
