A low-temperature, atmospheric pressure plasma was investigated to facilitate clean gasification of woody biomass with reduced tar and coke formation. When anhydrous sugars and lignin aromatic nuclei, as models of primary pyrolysis products of wood, were treated with dielectric barrier discharge plasma (gas temperature below 200°C), they were readily gasified to produce H₂ and CO. Although gasification of these compounds normally requires high temperatures of 600-700°C or higher, it was shown that the gasification reaction of wood-derived compounds can be facilitated by the plasma.
