Abstract:
1. A system for producing syngas from biomass materials, the system comprising: a receptacle adapted to receive a carbon-containing biomass feedstock; a gasification reactor adapted to receive the biomass feedstock from the receptacle and produce a syngas from the biomass feedstock, the gasification reactor comprising an inlet for the biomass feedstock, a syngas outlet for the syngas produced from the biomass feedstock, and an ash outlet for an ash that forms as the syngas is produced from the biomass feedstock; means for decreasing a moisture level of the biomass feedstock prior to the biomass feedstock being received by the gasification reactor from the receptacle so as to increase a carbon content of the ash; means for increasing a moisture level of a mixture of the biomass feedstock, the ash and gases while the biomass feedstock and the ash are within the gasification reactor so as to promote conversion of carbon in the biomass feedstock and the ash to a carbon-containing gas component of the syngas and decrease the carbon content of the ash; and means for controlling the decreasing and increasing means to selectively regulate the carbon content of the ash to a predetermined level between a level at which carbon is substantially absent from in the ash and a second level at which carbon is present in the ash.
