Abstract
A method of producing and treating synthesis gas in which a biomass-rich material is gasified in a gasifier containing a fluidized bed at a temperature that does not exceed 750° C. to produce a crude synthesis gas product. The crude synthesis gas then is quenched, scrubbed, and then subjected to at least one adsorption step to provide a clean synthesis gas. The clean synthesis gas then may be reformed catalytically to provide a synthesis gas with a desired H2:CO ratio, and/or may be employed in the synthesis of desired chemicals.
