摘要

The present invention relates to a method of controlling a catalytic reaction activity and which at the same time decomposed effectively the volatile organic compounds and the general VOCs that combines the halogen component can be detoxified (無毒 化) composite oxide catalyst and a method of manufacturing and using the same. .; And active compound oxide catalysts of the invention are two-component or three is more components as a component system catalyst and a main catalyst and co-catalyst and a support, the main catalyst to the active metal is Ru, the co-catalyst to the noble metal Pt and Sn, Zn , Cr, Ce, Co, Mn, Zr, W, a metal oxide of one or more components selected from the group consisting of transition metals such as V in the form of oxide, the support include Al ₂ O _3, TiO _2, ZrO _2, SiO as _second choice, and a support consisting of one or more substances of which there is a technical feature.; The catalyst of the present invention, main catalyst and co-catalyst 0.05~8wt% by manufactures dispersing 0.5~10wt% to the support, a two-component catalyst is one method for each of the active metal constituting the catalyst from excess solution impregnation and co-precipitation production, and to prepare a solution containing a predetermined amount of the metal precursor such that the amount of the metal oxide which require manufacturing and then dispersed in the support, and the multi-component catalyst coprecipitation a Ru-Sn / Al ₂ O ₃ and excess solution after the first produced in one way from impregnation complete firing, and technically characterized in that the manufactured through a process in which the final impregnated with a different co-catalyst, and then drying and firing.; And halogenated volatile organic compounds and volatile general control of the catalytic reaction that uses the high activity catalyst composite oxide of the present invention to eliminate oxidation of the organic compound is 150~450 ℃ reaction temperature, and the reaction gas space velocity (GHSV) 2,000~80,000hr ^{- 1,} characterized by the reaction in terms of the concentration of moisture 0.05~25vol% also to proceed.; High activity composite oxidation catalyst of the present invention are durable and VOCs oxidation activity as compared to noble metal catalysts, such as the high Pt and Pd oxidation activity for VOCs inferior this is rather characteristic that shows a better activity when HVOCs are mixed exhaust a bar, the solvent and washing step, HVOCs and VOCs generated in the various industrial fields such as petrochemical manufacturing processes in the same time can be removed by oxidation.; Then, the highly active compound oxide catalysts of the present invention group developed HVOCs catalyst losses and waste disposal problems, such as a two-component using solved by a transition metal not only environmentally friendly, or the active oxidation of the respective metal as a component system catalyst to be generated in the catalyst the wide compatibility width economically by reducing the precious metal content, with a synergistic effect can be expected.
