| 中文摘要: |
| 采用筛分、洗涤、吹扫等方法彻底清除废旧SCR催化剂中的积灰,得到基本不含灰尘的SCR催化剂,利用包括酸洗、碱洗等方法除去催化剂表面残存的微量杂质,将废SCR催化剂中的砷、铝、铁、钠、钾、硫、钙、硅等有害成分降低至新产品水平.对上述处理的催化剂进行补钒实验,通过再生处理,废SCR催化剂化学成分可以达到新产SCR催化剂水平. |
| 英文摘要: |
| The ash deposition in the waste SCR catalysts were completely removed by these method of screening,washing and purging,and the SCR catalysts with no dust were obtained.The use of acid,alkali and other methods to remove the catalyst surface residual trace impurities,the waste SCR catalyst in the arsenic,aluminum,iron,sodium,potassium,sulfur,calcium,silicon and other harmful components decreased to the level of new products.The catalysts for the above treatment were added to the vanadium experiment,and the chemical composition of the waste SCR catalyst could reach the level of the new SCR catalyst through the regeneration treatment. |
