摘要： The invention relates to a process and a catalyst composition for the destruction of volatile organic compounds (VOCs). The process includes the step of contacting the VOCs with an oxygen-containing gas in the presence of a catalyst which is a metal-exchanged, metal-impregnated aluminosilicate zeolite with at least one exchanged metal in the zeolite being selected from the group consisting of Ti, V, Cr, Co, Ni, Cu, Fe, Mo, Mn, Pd, and Pt, and at least one impregnated metal in the zeolite being selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Mo, Pd and Pt, and wherein the difference between the exchanged metal and the impregnated metal varies the temperature necessary to promote oxidation of the compounds and for a contact time sufficient to oxidize the compounds. The process reaction temperature can vary from about 100 DEG C to about 650 DEG C and the contact time can vary from about 0.01 to 20 seconds. Preferably, the reaction temperature is from about 150 DEG C to about 450 DEG C and the contact time is from about 0.1 to 1.0 seconds. The CO/CO2 ratio and the Cl2/HCl ratio in the gaseous effluent can be varied through selection of at least two impregnating metals with at least one exchanged metal in the aluminosilicate zeolite or by the use of at least one impregnating metal with at least two exchanged metals in the aluminosilicate zeolite.
摘要翻译：本发明涉及用于破坏挥发性有机化合物（VOC）的方法和催化剂组合物。该方法包括在催化剂存在下使VOC与含氧气体接触的步骤，催化剂是金属交换的金属浸渍的硅铝酸盐沸石，沸石中的至少一种交换金属选自Ti ，V，Cr，Co，Ni，Cu，Fe，Mo，Mn，Pd和Pt，沸石中的至少一种浸渍金属选自Ti，V，Cr，Mn，Fe，Co， Ni，Cu，Mo，Pd和Pt，并且其中交换的金属和浸渍金属之间的差异改变促进化合物氧化所需的温度和足以氧化化合物的接触时间。工艺反应温度可以在约100℃至约650℃之间变化，接触时间可以在约0.01至20秒之间变化。优选地，反应温度为约150℃至约450℃，接触时间为约0.1至1.0秒。气态流出物中的CO / CO 2比和Cl 2 / HCl比可以通过在铝硅酸盐沸石中选择至少两种浸渍金属与至少一种交换的金属或通过使用至少一种浸渍金属至少两种来改变在铝硅酸盐沸石中交换金属。
