Resumen : The silicon poisoning of a Pt/A120.~ catalyst was studied as a model system for industrial catalysts. Samples were contaminated using methyl- and phenylsubstituted polyoxysilane (MPSP) during the reforming of cyclohexane. It was found that silicon changes the chemisorption properties of platinum and does not affect its sinterization. However, coke has a more important effect in reducing the activity of the metallic function. On the other hand, silicon is harmful to the acid function, even in small amounts, suggesting that the poisoning is selective.
