Abstract:The adsorbent was prepared in microwave process by using refinery cinder and fly ash as the raw materials. Simultaneous desulfurization and denitrification tests were carried out in setting mechanism, with the object of apparent activation enery of adsorbent before or after modified by microwave. The purification mechanism of adsorbents is being discussed. The results show that the activation energy of adsorbents after modified by microwave depressed markedly. Microwave modification could enhance the desulfurization and denitrification acivating of adsorbents.
