Abstract Activated carbon for granular desulfurization and denitrification was prepared from raw coal, coal tar, asphalt and activated carbon powder. The effects of different activated carbon powder additions on the reconstituted strength and desulfurization performance were investigated. The research showed that with the increase of the amount of activated carbon powder, the wear resistance and compressive strength of the reconstituted desulfurization and denitration activated carbon showed a downward trend. The desulfurization value increased gradually with the increase of the activated carbon powder amount. The desulfurization and denitration activated carbon with excellent product performance and high resource recovery rate can be prepared under the condition that the carbon powder in the mixed coal powder was 15%-23%. The corresponding wear resistance, compressive strength and desulfurization value range were 97.01%-97.40%, 56.63-63.57 daN and 28.92-29.54 mg/g, respectively.
