METHOD OF OBTAINING BIOFUEL WHERE HEAT FROM CARBON-CARBON BONDS FORMATION REACTIONS IS USED FOR BIOMASS GASIFICATION REACTIONS PERFORMANCE Russian patent published in 2012 - IPC C10G2/00 C07C1/20 C07C27/06 C07C9/00 

FIELD: oil and gas production.

SUBSTANCE: one of the said versions includes a) performance of endothermal reaction of gasification with reagent from biomass at a temperature less or equal to approximately 750 K with synthetic gas obtaining, note that the temperature is ideal for synthetic gas disposal or for carbon-carbon bonds formation reaction; b) performance of exothermal reaction of synthetic gas disposal or reaction of carbon-carbon bonds formation with synthetic gas of stage (a) without any intermediate processing of synthetic gas of stage (a) at a temperature less or equal to the temperature of reaction of gasification performed at stage (a), where the reaction generates C₂-C₃₆ linear and branched hydrocarbons or oxygen-containing hydrocarbons and heat; c) use of heat generated at reaction of synthetic gas disposal or carbon-carbon bonds formation reaction of stage (b) in endothermal reaction of gasification of stage (a); d) performance of stage (a) and stage (b) with the use of only one layer of catalyst; and e) simultaneous performance of stage (a) and stage (b) with the use of one layer of catalyst, note that catalyst layer includes the mixture of catalysts or one catalyst that have dimensions and are composed to catalyse the reactions of both stages (a) and (b).

EFFECT: effective way from the point of energy to obtain fuel and chemicals from renewable resources of biomass.
