Abstract:
     A regenerated gas desulfurizing agent in solid state is prepared from ferrous sulfate (40-50%), calcium hydroxide (40-50%), copper sulfate (0.4-0.8%) and plaster (5-10%) through mixing the first three, addition of plaster when its pH value=9-10, solidifying at pH value=8-9 and shaping into strips. Its regeneration process is that after desulfurization, the strips are put in air with a certain humidity until the oxygen content in exhausted air reaches 21%. Its advantages are high desulfurizing effect and long service life.
