How to choose the catalyst for industrial exhaust treatment

Exhaust gas composition: Different exhaust gas composition requires the selection of different catalysts. For example, for volatile organic compounds (VOCs), platinum (Pt) or palladium (Pd) catalysts can be selected; For nitrogen oxides (NOx), copper-manganese-oxide catalysts can be selected.

Temperature range: The activity of the catalyst is usually related to the temperature at which it is used. Understand the temperature range in the waste gas treatment system, and select the appropriate catalyst activity temperature range to ensure that the catalyst has good catalytic activity and stability at the actual operating temperature.

Economy: The cost of the catalyst is one of the important factors to consider when choosing. The price, replacement cycle, regeneration capacity and environmental requirements of the catalyst should be comprehensively evaluated.

Stability and corrosion resistance: The components in the exhaust gas may contain some harmful substances, acidic substances or particles, which may have an adverse effect on the catalyst, reduce its catalytic activity or destroy the catalyst structure. Therefore, it is necessary to choose a catalyst with good stability and corrosion resistance.
