BIOMASS PROCESSING METHOD Russian patent published in 2020 - IPC C10B53/02 C10J3/00 B01J7/00 

FIELD: chemistry.

SUBSTANCE: invention relates to processing of biomass to obtain synthesis gas and biochar ash. Method is implemented by grinding of initial biomass to particle size of 100–200 mcm, mixing with water emulsion of heavy hydrocarbon raw material with water content of 18.0–25.0 wt. %, having water particle size of 10–30 mcm. Then obtained mixture is subjected to dispersion, formed suspension of mixture of ground biomass and aqueous emulsion of heavy hydrocarbon raw material is subjected to gasification at temperature 800–1200 °C, oxygen deficit ratio of 0.2 to 0.5 with subsequent direction of gasification products to separation and purification to produce synthesis gas and ash. In order to obtain synthesis gas with ratio H₂:CO of not less than 1.5 gasification, a suspension with ratio of biomass to water emulsion of heavy hydrocarbon material equal to 1.5–2.5:1 is subjected, and to obtain ash with carbon content of 25–60 wt. % of gasification, suspension is subjected to ratio of biomass: aqueous emulsion of heavy hydrocarbon material, equal to 5.0–7.5:1.

EFFECT: technical result consists in ensuring of target products with given characteristics by output and quality of gasification products control.
