High-performance high quality Volatile Organic Compounds VOCs
Catalyst
Product Description
For the purification of VOCs (volatile organic compounds) in
exhaust gas, the low - temperature catalytic combustion method is
employed. This process leverages the catalytic action of catalysts
to treat organic substances in the exhaust gas at low temperatures,
boasting high activity, energy conservation, and environmental
friendliness, thus achieving the goal of meeting emission
standards.
The catalytic combustion reaction is a typical gas - solid
catalytic reaction. Its essence lies in the fact that, at a certain
temperature, organic compounds (VOCs) in the exhaust gas are
adsorbed onto the surface of the catalyst. They then undergo a
catalytic oxidation reaction with oxygen in the air, being
completely oxidized into harmless carbon dioxide (CO₂) and water
(H₂O), while releasing reaction heat.
The catalyst can significantly lower the ignition temperature of
organic compounds, enabling flameless combustion. This not only
reduces preheating energy consumption but also minimizes the
generation of nitrogen oxides (NOₓ), making the entire purification
process more efficient and eco - friendly.
