SYNTHETIC GAS PRODUCTION METHOD Russian patent published in 2014 - IPC C01B3/38 B01J38/12 

FIELD: oil and gas industry.

SUBSTANCE: invention is referred to the area of petroleum chemistry and may be used for synthesis of methanol, dimethyl ether, hydrocarbons according to Fischer-Tropsch method. Methane-containing raw material is subjected to oxidative conversion at temperature of 650-1100°C in the riser. Miscrospheric or shredded catalyst based on metal oxides capable of multiple reduction-oxidative transfers is used as the oxidizer. Regenerated catalyst is recovered by its oxidation in the regenerator and addition to the riser in the bottom-up flow of methane-containing raw material; the riser operates in a through flow mode and duration of the raw material stay in the reaction area is 0.1-10 s. The regenerated catalyst exiting from the riser is separated from the product of synthetic gas and delivered to the regenerator. Catalyst regeneration is performed in fluidized, forced fluidized or semi-through flow by oxidation with oxygen-containing agent. The produced synthetic gas has H₂/CO ratio within the range of 7.5-2.5.

EFFECT: improvement of the product area efficiency, potential usage of hydrocarbon raw material containing carbon dioxide at reduced explosion and fire hazard and at low energy consumption.
