Volatile organic compounds (VOCs) are one of the main contributors to air pollution. To reduce anthropogenic emissions, it is necessary to improve existing techniques such as catalytic oxidation through the development of new cost‐effective catalysts. Although many studies deal with the development and testing of new materials, most are performed at laboratory scale, of which only a few study mixtures of VOCs. To assess their viability for industrial applications, further tests are required, namely, mixture tests at intermediate scale in relevant environment and extrapolated on an industrial scale. In this work, the catalytic performance of a new mixed oxide Co‐Al‐Ce was investigated towards the oxidation of the n‐butanol and toluene on a semi‐pilot scale (TRL 4). Single component and mixture experiments were performed for several concentrations at a fixed flow rate. A commercial catalyst Pd/γ‐Al₂O₃ was used as the benchmark to evaluate the performance of the mixed oxide. The Co‐Al‐Ce catalyst enables complete oxidation of n‐butanol at the same temperature as the reference catalyst. Moreover, it provides a better selectivity for n‐butanol, while providing an equivalent one for the oxidation of toluene. In mixtures, the presence of n‐butanol promotes the oxidation of toluene for both catalysts but more significantly for the Co‐Al‐Ce catalyst. The presence of toluene inhibits the oxidation of n‐butanol for the Co‐Al‐Ce and promotes it for high conversions of n‐butanol for the Pd/γ‐Al₂O₃ catalyst.

以半试规模评估混合氧化物对VOC的催化氧化性能†

挥发性有机化合物（VOC）是造成空气污染的主要因素之一。为了减少人为排放，有必要通过开发新的具有成本效益的催化剂来改善现有技术，例如催化氧化。尽管许多研究涉及新材料的开发和测试，但大多数研究都是在实验室规模进行的，其中只有很少的VOC研究混合物。为了评估其在工业应用中的可行性，需要进行进一步的测试，即在相关环境中以中等规模进行混合物测试，并以工业规模进行推断。在这项工作中，研究了一种新型混合氧化物Co-Al-Ce对n氧化的催化性能。半试规模的丁醇和甲苯（TRL 4）。以固定流速对几种浓度进行了单组分和混合物实验。市售催化剂的Pd /γ-Al系₂ ö ₃用作基准来评估混合氧化物的性能。Co-Al-Ce催化剂可在与参考催化剂相同的温度下完全氧化正丁醇。此外，它提供了更好的正丁醇选择性，同时提供了与甲苯氧化相当的选择性。在混合物中，正丁醇的存在会促进两种催化剂的甲苯氧化，但对于Co-Al-Ce催化剂则更为明显。甲苯的存在会抑制n的氧化丁醇的Co-Al系-Ce和促进它的高转化率Ñ丁醇为钯/γ-Al系₂ ö ₃催化剂。
