In the field of industrial waste gas treatment, the removal of volatile organic compounds (VOCs) has always been a key issue faced by environmental protection technologies. Nowadays, catalytic activated carbon, as a new adsorbent material, is completely changing the traditional VOCs treatment methods.
The difference between catalytic activated carbon and conventional activated carbon that relies solely on physical adsorption is that catalytic activated carbon can undergo catalytic and oxidation reactions at lower temperature conditions, and can more thoroughly decompose adsorbed harmful oxides into carbon dioxide and water. This feature significantly improves the ability of catalytic activated carbon to handle complex and high concentration VOCs waste gases, especially in the treatment of waste gases from the chemical, spraying, and printing industries.
In the field of VOC adsorption, the difference between catalytic activated carbon and traditional activated carbon is that traditional activated carbon needs to be cleaned after VOC adsorption saturation, such as replacement or high-temperature desorption regeneration, to restore its cleaning ability, while catalytic activated carbon has a certain self-cleaning ability and a longer service life compared to traditional activated carbon. When the exhaust gas passes through a filter bed loaded with catalytic activated carbon, the adsorption and catalytic degradation of the exhaust gas will work together, which not only improves the efficiency of VOC adsorption, but also reduces the risk of secondary pollution to the environment from the source.
