METHOD AND UNIT TO RECOVER SYNTHESIS GAS FROM BIOMASS Russian patent published in 2008 - IPC C10J3/04 

FIELD: oil and gas production industry.

SUBSTANCE: invention is related to method and unit to recover synthesis gas from biomass. According to the invention the method includes stages of fuel gas burning in combustion unit (4) with production of hit flue gases (7), passage of flue gases (7) via thermal storage device (1) to heat-up the thermal storage device (1) to high temperature, heat-up of gaseous medium located there and use of this medium to heat-up biomass in the reactor (2) to high temperature with production of synthesis gas, supply of produced synthesis gas for heating to thermal storage device, removal, at least, of part of produced synthesis gas via thermal storage device (1), biomass reactor (2) and back to the thermal storage device (1).

EFFECT: reduced energy consumption and improved environmental properties of the synthesis gas recovery method with small content of admixtures.
