METHOD FOR PREPARING A METAL OXIDE CATALYST FOR DEODORIZATION

摘要

PURPOSE: A method for manufacturing metal oxide catalyst for deodorization is provided to save costs required for manufacturing catalyst by naturally drying the catalyst without a drying furnace. CONSTITUTION: A method for manufacturing metal oxide catalyst for deodorization includes the following: 1-50 weight% of manganese oxide of nano particles based on manganese nitrate solution is diluted into a colloidal form. The colloidal solution of the manganese nitrate containing manganese oxide at a temperature of 30 to 70 degrees Celsius is prepared. 10-20% of potassium permanganate is molten in distilled water of 65 to 75 degrees Celsius to obtain an aqueous solution. 1-30% of titanium dioxide of nano particles is diluted in the distilled water such that the titanium dioxide becomes a colloidal form. The titanium dioxide of colloidal form is mixed with the potassium permanganate and is heated in a double boiler. The mixture solution at a temperature of 50 to 70 degrees Celsius is prepared. 1-50% of auxiliary catalyst is diluted in distilled water of 50 to 80 degrees Celsius such that the auxiliary catalyst becomes a colloidal form, and an auxiliary catalyst impregnated support is dried.
