The present invention discloses a desulfurization denitrifier, wherein the desulfurization denitrifier mixes a polyol and / or a polyol material, a polycarboxylic acid material and an alkaline material, and heats it to 90 ° C. or higher to obtain a large molecule or Obtained by producing ether and / or ester materials of the polymer. The desulfurization denitrifiers of the present invention have a wide range of industrial uses and can be used simultaneously or separately to remove sulfur dioxide and nitrogen oxides in gases, and are renewable and energy consuming as compared to conventional desulfurization and / or denitrification agents. Less, no secondary pollution, low running cost, high desulfurization denitrification efficiency and simple operation. |
