A metal catalyst and its preparation and application for the treatment of acetone, which granulates by adding hydrophobic adhesive to zeolite powder, so that hydrophobic zeolites that are not easily affected by water and gas are prepared as catalyst carriers, then non-noble metals (iron, manganese or their combination) was loaded on the catalyst carriers by wet immersion and ultrasonic oscillation to obtain the metal catalyst, based on the method of adsorption and catalyst combustion, the metal catalyst are used to continuously treat acetone-containing waste gas, the acetone is concentrated by adsorption of the metal catalyst, and then converted into carbon dioxide and water by low temperature combustion at a temperature below 350 DEG C, so as to achieve the purpose of converting acetone by using the zeolite catalyst loaded with non-noble metals and low temperature catalyst method, effectively reducing the energy and cost for the treatment of acetone waste gas.
