 The production of biofuels from renewable sources is a major challenge in research. Methanol, ethanol, dimethyl ether, DME, synthetic natural gas, SNG, and hydrogen can be produced from syngas which is the result of the gasification of biomasses. Synga's composition varies according to the gasification technology used, such as fixed bed reactors, fluidized bed reactors, entrained flow reactors, the feedstock characteristics, and the operating parameters. This paper presents a review of the predominant biomass gasification technologies and biofuels obtained from syngas by biomass gasification.
