Abstract
Coal and solid fuels derived from industrial wastes sometimes contain a small amount of mercury compounds. In conmbustion processes, gaseous elemental mercury passes through the stack and releases into the atmosphere. Mercury emissions in the combustion processes have been focused as one of upcoming air pollutants. In this work, it is the purpose to use wastes (sewage sludge, woody biomass and municipal waste) as an adsorbent of elemental mercury. We conducted mercury adsorption experiment used carbonized sewage sludge, carbonized biomass and carbonized municipal waste as adsorbents. As a result, the mercury adsorption ratio of carbonized municipal waste was the largest.
