  • Aluminum

    In the present work, aluminum oxide and aluminum sulfate were tested as additives to enhance the leaching of coal pyrite during SO 2 removal in a bubbling reactor. It was found that adding aluminum oxide or aluminum sulfate into the coal slurry could increase the coal pyrite conversion and SO 2 removal efficiency. The leaching process could be described by the reaction-controlled shrinking core model.
