为了提高微波辐照活性炭同时脱硫脱硝技术的脱除效率,降低能耗并增加还原反应的选择性,选择几种催化剂负载于活性炭上,研究了其对同时脱硫脱硝的影响.结果表明:微波功率越大,活性炭床所能达到的温度越高,反应温度也越高;催化剂的加入提高了同时脱硫脱硝的效率,且不同催化剂所产生的效果不同,在420W的微波功率下,铜基催化剂能促进微波辐照活性炭脱硝,却不利于微波辐照活性炭脱硫,而Mn(NO3)2可作为工业上的最佳催化剂,使同时脱硫脱硝的效率提高到95%左右.
In order to improve the removal efficiency of simultaneous desulfurization and denitrification by microwave irradiation and to reduce the energy consumption and increase the selectivity of the reduction reaction, several catalysts were selected and supported on activated carbon to study their effects on simultaneous desulfurization and denitrification. The results show that microwave power The larger the temperature that the activated carbon bed can reach is, the higher the reaction temperature is. The addition of catalyst increases the efficiency of simultaneous desulfurization and denitrification, and the effect of different catalysts is different. Under the microwave power of 420W, the copper-based catalyst energy However, Mn (NO3) 2 can be used as the best catalyst in the industry, and the efficiency of simultaneous desulfurization and denitrification can be increased to about 95%.
