摘要
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.
To improve the removal efficiency of simultaneous activated carbon-based desulfurization and denitration under microwave irradiation,and to reduce the energy consumption and increase the selectivity of reduction reaction,several catalysts were chosen and loaded on the activated carbon to study their influences on the simultaneous desulfurization and denitration.Results show that the greater the microwave power is,the higher the temperature of activated carbon bed and the reaction temperature will be; the adding of catalyst can improve the efficiency of simultaneous desulfurization and denitration,and different catalysts produce different effects; under the microwave power of 420 W,copper-based catalysts can promote the activated carbon-based denitration but inhibit the activated carbon-based desulfurization under microwave irradiation.As the optimal catalyst in industry application,Mn （NO3）2 can help to improve the simultaneous desulfurization and denitration efficiency up to 95％.
