Method for enhancing activity of raw material for preparing nickel carbonyl

The invention provides a method for enhancing activity of a nickel carbonyl raw material, and relates to an improved method for enhancing carbonylation rate by performing activating treatment on a nickel raw material. The method is characterized by comprising the following step: introducing SO2-containing hydrogen into a reducing furnace to react with the nickel raw material in the reducing furnace, thereby enhancing the activity of the nickel carbonyl raw material. The method for enhancing activity of the nickel carbonyl raw material is simple to operate and easy to implement, and has obvious effect. The detection proves that the sulfur content in the nickel raw material is increased from 0.14-0.43% to 1.9-2.42%, and the reaction rate is obviously changed in the carbonylation synthesis process, thereby finally enhancing the carbonylation rate of the nickel raw material.
