石灰石‑石膏湿法烟气脱硫添加剂及其制备方法
摘要：
本发明提出了一种石灰石‑石膏湿法烟气脱硫添加剂，按照重量百分数计算，包括以下原料：赤泥1～2％，铁氧体磁粉0.6～1.2％，硫酸铝1～2％，十二烷基苯磺酸钠20～30％，己二酸30～50％，催化氧化剂0.5～1.9％，余量为水。制备方法，包括以下步骤：首先将赤泥、铁氧体磁粉与己二酸的混合物在40～50℃下混合搅拌均匀，然后降温至室温再加入硫酸铝、十二烷基苯磺酸钠、催化氧化剂以及水进行混合搅拌均匀即可。该添加剂脱硫效率高，脱硫率高达96.5％。
摘要（英）：

The invention proposes a limestone-gypsum wet flue gas desulfurization additive, made from the following materials in percent by weight: 1-2% of red mud, 0.6-1.2% of ferromagnetic oxide powder, 1-2% of aluminum sulfate, 20-30% of sodium dodecyl benzene sulfonate, 30-50% of adipic acid, 0.5-1.9% of a catalytic oxidant and the balance of water. A preparation method comprises the following steps: mixing and stirring well a mixture of red mud, ferromagnetic oxide powder and adipic acid at 40-50 DEG C, cooling to room temperature, adding aluminum sulfate, sodium dodecyl benzene sulfonate, catalytic oxidant and water, and mixing and stirring well. The additive is high in desulfurization efficiency, up to 96.5%.
