Abstract
A method for producing syngas from preferably vegetal biomass is described. The method provides for the use of a fixed bed gasifier, equipped with two reactors. The biomass is fed to both reactors together with a primary flow rate of air. Advantageously, the method according to the present invention is different from the known art since a secondary flow rate of air is withdrawn from the first reactor at the area where the biomass dries, and fed to the second reactor at the area where the biomass dries, and vice versa, alternately during time. Alternatively, an oscillating air flow is created in each reactor. The achievable result is a greater syngas production, but not exclusively. The syngas quality is improved too, since the biomass has a longer time for completing the gasification reactions.
