Abstract: An autothermal process of concentric bubbling fluid double bed for the production of syngas by gasification with biomass steam, in the presence of a granular material includes: continuous gasification under stationary bed condition of said granular material in bubbling fluidisation regime of biomass with water vapour with thermochemical transformation of the fuel into raw syngas and char, the raw syngas including heavy hydrocarbons in the steam state and any harmful compounds in traces, in a first reaction volume; combustion in bubbling fluidised bed with air of the char and of auxiliary fuel in a second reaction volume; the transfer velocity of the granular material between the first and second reaction volumes being such that the thermal difference does not exceed 20° C.; separation from the raw syngas by hot filters; and elimination of any harmful compounds in traces.

Abstract: The present invention relates to a gasification apparatus for generating syngas from gasifiable feedstock material, said apparatus comprising a vessel having a feedstock inlet, an inlet for a gaseous gasifying medium, an outlet for exhausted feedstock material and a syngas outlet; a gasifying reactor accommodated in said vessel and in fluid communication with said feedstock inlet, said outlet for exhausted feedstock material and said inlet for said gasifying medium of said vessel; and a filtering unit accommodated in said vessel and having an upstream side and a downstream side, said upstream side of said filtering unit being in fluid communication with said reactor and said downstream side thereof being in fluid communication with said syngas outlet.
