WebOct 10, 2024 · The Fe-BEA catalyst was coated onto a cylindrical rolled metallic substrate made of flat and corrugated thin (50 μm) AlCr foils (cell density of 600 cpsi). The coating load was about 150 g/L (40 g/m 2 ). The dimensions of the tested sample were L = 20 mm, D = 12.5 mm, V = 2453 mm 3. WebOct 13, 2016 · Because the weak acid sites behave as anchoring sites for Fe ions, the catalytic activity also increased as the treatment time increased. However, extended exposure of BEA to acid decreased the catalytic activity of the Fe-BEA catalyst somewhat, and decreased the silanol groups and weak acid sites.
