METHOD OF PRODUCING HYDROGEN- AND/OR CARBON MONOXIDE-ENRICHED GAS Russian patent published in 2005 - IPC

FIELD: gas production technologies.

SUBSTANCE: invention relates to production of hydrogen-rich and/or carbon monoxide-rich gases, which is accomplished in reactor having upper and lower parts and involves introducing hydrocarbon feedstock preheated to 400-700°C into upper part of reactor. In this part of reactor, hydrocarbon feedstock is mixed with water steam and oxygen-containing atmosphere resulting in a partial oxidation of feedstock. Partially oxidized feedstock, if necessary, comes into contact with reforming catalyst located in lower part of reactor in presence of water steam. At the same time, a part of partially oxidized feedstock contacts with steam reforming catalyst disposed at least on the surface of upper part of reactor. Mixing of feedstock with water steam and oxygen-containing atmosphere is effected in amounts providing oxygen-to-carbon molar ratio between 0.5:1 and 0.7:1 and water steam-to-carbon between 0.5:1 and 1.5:1.

EFFECT: considerably reduced formation of carbon black in combustion zone under critical process conditions.
