METHOD OF STEAM CATALYTIC CONVERSION OF NATURAL GAS INTO SYNTHESIS-GAS AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2008 - IPC C01B3/38 

FIELD: production of synthesis-gas.

SUBSTANCE: proposed method is carried out at temperature of 750-900 C due to external heating of tubular furnace reaction tubes filled with catalyst; mixture of natural gas and superheated steam is fed to reaction tubes. External heating of reaction tubes filled with catalyst is first performed by burning the natural gas in air; after attaining the required mode of operation, external heating is carried out by burning the synthesis-gas fed from tubular furnace outlet to reaction tube external heating chamber. Device proposed for realization of this method includes tubular furnace with reaction tubes filled with catalyst, chamber for mixing the natural gas with superheated steam and external heating chamber for heating the reaction tubes filled with catalyst for maintenance of conversion process; heating chamber is provided with air inlet. Device is also provided with gas change-over point whose one inlet is used for delivery of natural gas fed to chamber of external heating tubular furnace reaction tubes during starting the mode of steam conversion process; other inlet of gas change-over point is used for delivery of synthesis-gas from tubular furnace outlet through distributing synthesis-gas delivery point. Device is also provided with regulator for control of delivery of synthesis-gas to reaction tube external heating chamber required for combustion.

EFFECT: enhanced economical efficiency of process.
