MANUFACTURE OF CHEMICALS AND FUELS FROM BIOMASS Russian patent published in 2017 - IPC C10G3/00 C07C1/20 C10L1/02 

FIELD: chemistry.

SUBSTANCE: invention relates to methods for conversion of biomass into fuels and chemicals. A method for converting of biomass into fuels and chemicals comprises: providing biomass feed stream as a solid biomass slurry containing solvent and biomass components - cellulose, hemicellulose and lignin; implementation of catalytic reaction of biomass feed stream with hydrogen and a catalyst for decomposition at the decomposition temperature and pressure to produce a product stream comprising a vapor phase, liquid phase and solid phase, wherin the vapor phase comprises one or more volatile oxygenates C₂₊O_1-2, the liquid phase contains water and one or more oxygenated hydrocarbons C₂₊O₂₊, and the solid phase contains ash components painted dry residues, protein materials and inorganic products; separating of volatile oxygenates C₂+O_1-2 from the liquid phase and the solid phase; and the implementation of catalytic reactions of volatile oxygenates C₂₊O_1-2 in the presence of the condensation catalyst at condensing temperature and pressure to obtain a compound C₄₊, containing an element selected from the group consisting of alcohol C₄₊, ketone C₄₊, alkane C₄₊, alkene C₄₊, cycloalkane C₅₊, cycloalkeneC₅₊, aryl, condensed aryl and their mixtures. Two process versions are provided.

EFFECT: invention provides obtaining fuel compositions and solid chemicals from solid biomass.
