AI Technical Summary
Existing catalysts are inefficient and have insufficient durability when decomposing perfluoro compounds, making them difficult to effectively decompose at lower temperatures. Long-term exposure to perfluoro compounds will cause damage to the catalyst surface structure and affect its service life.
A honeycomb catalyst containing aluminum oxide is used, with a density of more than 300 g/L, a channel density of 30 to 150 CPSI, a porosity of 10 to 100, and a surface area of more than 40 m2/g. The contact area and durability of the catalyst are improved by adjusting the pore and channel structure.
It improves the decomposition efficiency of perfluoro compounds and the life of the catalyst, and can effectively decompose perfluoro compounds at lower temperatures, reduce pressure losses, and extend the service life of the catalyst.
