摘要： A method for treating cooking fumes to oxidize oxidizeable particulate and gaseous components thereof includes contacting the fumes with a catalytic material containing ceria and alumina each having a BET surface of at least about 10 m.sup.2 /g, for example, ceria and activated alumina in a weight ratio of from about 1.5:1 and 1:1.5 and a BET surface area of from about 25 m.sup.2 /g to 200 m.sup.2 /g. Optionally, a catalytic metal component such as platinum or palladium may be included in the catalytic material. The foodstuffs cooking fumes are contacted with the catalyst composition (22 or 40) at a temperature of 200.degree. C. to 600.degree. C. to promote the oxidation of both particulate (atomized) animal and/or vegetable oils and fats and oxidizeable gas phase components of the fumes. Optionally, a separate, supplemental gas phase oxidation catalyst (42) may be used in conjunction with and downstream of the above-described catalyst (40) to provide a two-catalyst system for treating cooking fumes.

摘要翻译： 用于处理烹饪烟雾以氧化可氧化颗粒和气体组分的方法包括使烟雾与含有至少约10m 2 / g的BET表面的二氧化铈和氧化铝的催化材料接触，例如二氧化铈和活性氧化铝，其重量 比例为约1.5:1和1:1.5，BET表面积为约25m 2 / g至200m 2 / g。 任选地，催化金属组分如铂或钯可以包括在催化材料中。 烹饪烟雾的食物在200℃至600℃的温度下与催化剂组合物（22或40）接触以促进颗粒（雾化）动物和/或植物油和脂肪和可氧化气相的氧化 烟雾成分。 任选地，单独的补充气相氧化催化剂（42）可以与上述催化剂（40）结合使用和下游使用，以提供用于处理烹饪烟雾的双催化剂体系。
