Pt-Sn catalysts - Opis:
- Coke deposit is produced from ethylene on the surface of the platinum and platinum-tin catalysts supported on two various AI2O3, SiO2 and SiO2-Al2O3. The coke amount and the structure depend on the type and the amount of the components introduced onto the catalyst support and on the type of the support. It has been found that the surface area of the support has no significant effect on the type of species in the coke deposit. The analysis of the FT-IR spectra has shown the presence of different species on the surface of the catalysts, including carboxyl groups, pseudo-graphite (polyaromatic) structures, polyphenylene groups, acetyl groups, carbonyl groups of acetone and formate type, enol species.
