Air-blown Wood Gasification in a Large Fluidized Bed Reactor

Wood gasification in the Gasification Research on Wood (GROW) pilot plant at the University of Missouri-Rolla has been described. The effects of various types of reactors, feed materials, methods, moisture contents, residence times, and bed temperatures on quality and quantity of product gas were studied. It was found that the car- bon-to-nitrogen ratio was a major factor in this process. Empirical correlations and design methods are presented. The economics for the proposed system were evaluated
