lower temperatures than conventional thermal oxidation. It is used for the energy-efficient purification of pollutant-laden exhaust air streams containing volatile organic compounds (VOCs) and carbon monoxide (CO). The pollutant-laden exhaust air is first heated to the <strong>reaction temperature (depending on the catalyst, pollutant mixture and emissions target)<\/strong> and then passed through the catalyst. The catalyst promotes oxidation of carbon monoxide to CO\u2082 and of hydrocarbon VOCs mainly to CO\u2082 and water.  <\/p>\n<p>The energy released can be used to increase system efficiency with a <strong>recuperative heat exchanger<\/strong> for preheating the raw gas, thereby reducing the auxiliary energy requirement.<\/p>\n<p>CATOX is particularly suitable for applications with low to medium pollutant concentrations where low energy consumption and high purification performance are prioritized. A prerequisite for long-term operation is exhaust air that is largely free of dust and catalyst poisons. <\/p>\n<p>The lower oxidation temperatures compared to an RTO and the associated shorter heat-up times are particularly attractive for production facilities that do not operate daily or have interruptions.<\/p>\n<\/div><\/div>\n<\/div>\n\n<div class=\"et_pb_column_8 et_pb_column
