Abstract:
    A method for removing sulfur compounds from gasification product gas during gasification of carbonaceous materials in a fluidized bed, agglomerating discharge reactor and converting harmful and unstable sulfur compounds to an environmentally acceptable form for safe disposal. Particulate sulfur fixation agent is introduced into an ash agglomerating fluidized bed gasifier along with carbonaceous feed solids and reacts with gaseous sulfur compounds formed when gasifying feed solids under reducing conditions in the fluidized bed. Unstable sulfur compounds formed by reaction with the fixation agent are then converted to a stable, environmentally disposable, solid in a lower oxidizing portion of the gasifier for discharge with the ash.
