    • PURPOSE: A method for activation-regenerating a waste activated carbon catalyst for selective catalyst reduction(SCR) is provided to prevent the waste of resources by expanding the life expectancy of waste activated carbon. CONSTITUTION: A method for activation-regenerating a waste activated carbon catalyst for SCR includes the following: waste activated carbon is washed using surfactant; the washed waste activated carbon is acid-treated using hydrochloric acid; and the waste activated carbon is further ammonia-treated. In the washing process, the waste activated carbon is introduced into a surfactant aqueous solution and is washed under the temperature of 60-90 degrees Celsius, the pressure of 0.01-2.0 atm for 30 to 60 minutes. In the acid treating process, the waste activated carbon is introduced into 2N hydrochloric acid under a temperature of 60-80 degrees Celsius and is stirred. The waste activated carbon is introduced into distilled water and is stirred for 1 to 3 hours to be further washed.
    • 目的:提供一种用于活性再生废催化剂还原活性炭催化剂(SCR)的方法,以通过扩大废活性炭的预期寿命来防止资源浪费。 构成:用于SCR的废活性炭催化剂的活化再生方法包括:废活性炭用表面活性剂洗涤; 洗涤后的废活性炭用盐酸进行酸处理; 并将废活性炭进一步进行氨处理。 在洗涤过程中,将废活性炭引入表面活性剂水溶液中,并在60-90摄氏度的温度,0.01-2.0大气压的压力下洗涤30至60分钟。 在酸处理过程中,将废活性炭在60-80摄氏度的温度下引入2N盐酸中并搅拌。 将废活性炭引入蒸馏水中并搅拌1至3小时以进一步洗涤。
