The invention discloses desulfurization and
denitrification active carbon and a preparation method and device thereof. The
active carbon is prepared from the following raw materials: raw
coal,
coke powder,
coal tar,
nickel powder,
ferric oxide powder,
zinc oxide powder and deionized water; the preparation method comprises the following steps that the raw materials are blended and stirred to be uniform and then subjected to bar depression treatment, a first bar depression
raw material is obtained, the first bar depression
raw material is ground to be powder, the ground
raw material is obtained,the ground raw material is subjected to bar depression treatment, a secondary bar depression raw material is obtained, the secondary bar depression raw material is subjected to
drying treatment underthe condition of air isolation, a carbonized raw material is obtained, the carbonized raw material is dipped in
phosphoric acid, an activated raw material is obtained, the activated raw material is dried and subjected to spray treatment, and the desulfurization and
denitrification active carbon is obtained. The preparation device comprises a stirring device, a feeding device and a pressing device. The desulfurization and
denitrification active carbon and the preparation method and device thereof increase the
sulfur capacity of the active carbon and the
oxygen-containing groups on the surface,and remarkably improve the desulfurization and denitrification effect of the active carbon.
