The invention discloses a denitrification agent, a preparation method and a dry-method denitrification method, and relates to the technical field of smoke treatment. The denitrification agent is prepared from: 1 to 15 percent of macromolecular resin, 30 to 70 percent of urea, 1 to 15 percent of sodium hydrogen carbonate, 5 to 20 percent of silicon dioxide, 10 to 20 percent of kaolin, 5 to 10 percent of talcum powder, 5 to 20 percent of diacetonitrile, and 1 to 30 percent of bentonite. The method comprises the following steps: mixing all the raw materials to obtain the denitrification agent. The denitrification method comprises the following steps: spraying the denitrification agent into a temperature area of 750 to 1000 DEG C in a hearth, reacting, and removing the nitrogen oxide in the smoke. The denitrification efficiency of the denitrification agent for the smoke is at least 80 percent or above; the SCR process can be completely substituted; the denitrification cost can be reduced;the operation difficulty can be reduced; the denitrification efficiency can be improved, and the emission standard of the nitrogen oxide can be reached.
