  • The semi-coke adsorbents were prepared by loading metal oxide on a cheap semi-coke material modified through nitric acid oxidation and high temperature heat treatment. The desulfurization and denitrification and regeneration abilities were investigated. BET, TEM and SEM were employed to explore the effecting factors on the performance of the adsorbents. The results show that the adsorbents have a good denitrification activity and a regeneration ability with water washing when using NO-O2-N2 simulated flue gas. And the adsorbents exhibit an excellent desulfurization activity, especially with the coexistence of NO. However, its denitrification activity decreases rapidly and can not be regenerated effectively for the tests with SO2-O2-N2 and SO2-NO-O2-N2 simulated flue gas. The characterization results indicate that both SO2 and NO can be adsorbed on the adsorbents, and the main reasons for the adsorbents deactivation are its porous channel plugging and surface property variation.
