Abstract
PURPOSE:To reduce the cost of equipment by specifying the equivalent diameter of the through holes in a catalyst, the thickness of the cells and the rate of opening. CONSTITUTION:The shape of a catalyst used to decompose waste water into nitrogen, CO2 and water by wet oxidation is so regulated that the through holes have 2-20mum equivalent diameter, the cells have 0.5-3mm thickness and the rate of opening is 50-80%. The catalyst is obtd. by kneading powder of titania, zirconia, silica, alumina, etc., with a molding assistant and a proper amt. of slowly added water, molding the kneaded material into a honeycomb shape with a press molding machine, drying and calcining the molded body. The catalyst can maintain high activity over a long period.
