Abstract: PURPOSE: Provided is a catalyst for decomposition of toxic compounds including polychlorinated dibenzo-p-dioxin/polychlorinated dibenzofuran, polychlorinated biphenyl, chlorinated benzene, chlorinated phenyl, nitrogen oxides and volatile organic compounds. The present catalyst displays optimal catalytic activity in the temperature range of 200 to 350°C in 5-31vol.% oxygen atmosphere. CONSTITUTION: The catalyst is prepared by wash-coating 6-12wt.% of TiO2 and 10-30wt.% of Al2O3 on the surface of a cordierite honeycomb(based on the total weight of the catalyst) and supporting a complex substrate of the cordierite-titanium dioxide-alumina with 1-6wt.% of V, based on the weight of titanium dioxide, and sequently the complex substrate is dried at the temperatures of 100 to 300°C and calcined at the temperatures of 400 to 600°C for 1-5 hours. The preparation of the catalyst further includes, before above drying and calcination process, the step of supporting at least one metal or metal oxides selected from Mo, W, Pd, and their oxides on the complex substrate. The amount of these metals or metal oxides is less than 9wt.% based on the weight of titanium dioxide.
Abstract translation: 用途：提供有毒化合物分解催化剂，包括多氯代二苯并对二恶英/多氯代二苯并呋喃，多氯联苯，氯代苯，氯代苯基，氮氧化物和挥发性有机化合物。 本催化剂在5-31体积％的氧气氛中在200-350℃的温度范围内显示出最佳的催化活性。 构成：通过在堇青石蜂窝体的表面上涂覆6-12重量％的TiO 2和10-30重量％的Al 2 O 3（基于催化剂的总重量）并且支撑堇青石的复合基底来制备催化剂 - 二氧化钛 - 氧化铝，其具有基于二氧化钛重量的1-6重量％的V，并且随后将复合基材在100-300℃的温度下干燥并且在400-600℃的温度下煅烧。 ℃下1-5小时。 在上述干燥和煅烧过程之前，催化剂的制备还包括将至少一种选自Mo，W，Pd及其氧化物的金属或金属氧化物负载在复合基材上的步骤。 基于二氧化钛的重量，这些金属或金属氧化物的量小于9重量％。
