Si-TOLERANCE OF IRON DOPED Pt/ALUMINA CATALYST IN THE TOTAL OXIDATION OF VOC abstract
In the present study the effects of addition of iron on the catalytic activity and Sitolerance of Pt/ -Al2O3 in the total oxidation of volatile organic compounds were investigated. Preliminary results showed that there is a noticeable improvement effect on Si-tolerance of catalyst, particularly for short term poison exposure. Bulk analysis of deposited silicon on the catalyst surface indicated that both Pt/ -Al2O3 and iron-doped pellets had almost the same silicone uptakes. Deactivation of catalyst was reversible and much faster for iron doped sample. The promoting effect of iron was related to blocking of fewer Pt sites when iron is present at the surface of the catalyst.
