摘要

The effects of gas phase temperature and residence time on the products of the pyrolysis/steam reforming of red alder pellets have been investigated. Of the conditions studied, residence times of 6 to 9 seconds at 700 exp 0 C produces the largest quantity of medium Btu gas from the pellets. The quantity of gas produced is less than one-half that obtained from cellulose under similar conditions. This relative paucity of gas yield may be an artifact of the pelletizing process, or it may reflect an inherent difficulty in gasifying red alder wood. Of course, more extreme conditions than examined here could be used to obtain higher gas yields. However, the high cost of reactors utilizing extreme conditions militates against their use for biomass gasification. More research is needed to determine the desirability of pelletized fuels for gasification proceses, and th optimal conditions for steam pyrolysis/gasification of biomass. (ERA citation 04:032748)
