FIELD: chemistry.
SUBSTANCE: method involves: (a) carrying out an endothermic gasification reaction with a biomass reactant at a temperature lower than or equal to about 750 K, to yield synthesis gas, wherein the temperature is optimum for the synthesis gas recycling reaction or for the carbon-carbon forming reaction; (b) carrying out an exothermic synthesis gas recycling reaction or carbon-carbon bond forming reaction with the synthesis gas from step (a) without any intermediate treatment of the synthesis gas from step (a) at a temperature higher than or equal to the temperature of the gasification reaction carried out at step (a), wherein the reaction produces C2-C36 linear or branched hydrocarbons or oxygen-containing hydrocarbons, and heat; and (c) using the heat generated from the synthesis gas recycling reaction or carbon-carbon bond forming reaction of step (b) in the endothermic gasification reaction of step (a).
EFFECT: use of the invention provides an energy-efficient way of producing fuel and chemicals from renewable biomass resources.
