METHOD OF PRODUCING AND USING BIOMASS MATERIAL Russian patent published in 2024 - IPC C01B32/05 C01B32/324 C01B32/336 C01B32/378 B01J23/72 B01J23/745 C10L5/44 

FIELD: various technological processes.

SUBSTANCE: invention relates to a method of producing biomass material, comprising the following steps: 1) grinding waste agricultural and forestry wastes, placing the crushed materials into a carbonisation device to obtain a preliminary prepared carbide; 2) adding a copper-iron catalyst including chalcopyrite and iron ore to produce a mixed material; 3) under conditions of inert gas introduction of water vapour, low-temperature carbonisation of mixed material to produce charcoal biomass; 4) under inert gas conditions introduction of gaseous ammonia, high-temperature carbonisation of biomass charcoal obtained at step 3), then natural cooling to room temperature, purification and drying to obtain biomass material. Invention also relates to use of biomass material.

EFFECT: biomass material reduces content of sulphur and ash and has high activity and high reduction efficiency.
