FIELD: chemistry. ^ SUBSTANCE: described are methods of producing propylene glycol, ethylene glycol and other polyatomic alcohols, diatomic alcohols, ketones, aldehydes, carboxylic acids and alcohols from biomass using hydrogen obtained from the biomass. Methods involve reaction of a portion of an aqueous stream of the crude solution of the biomass in the presence of a catalyst under aqueous phase reforming conditions to obtain hydrogen, and then reaction of hydrogen and the crude aqueous solution in the presence of a catalyst to obtain propylene glycol, ethylene glycol and other polyatomic alcohols, diatomic alcohols, ketones, aldehydes, carboxylic acids and alcohols. ^ EFFECT: described methods can be realised at lower temperature and pressure, and enable to obtain oxygen-containing hydrocarbons without the need for supplying hydrogen from an external source. ^ 62 cl, 16 ex, 11 dwg |
