Abstract
The rate of propene hydrogenation has been measured, in a flow system, over platinum supported on inorganic materials (Al2O3 and MgO) and polyamides (Nylon 66 and Nylon 610). The effect of adding tin to Pt/Nylon 66 has also been investigated. The orders of reaction with respect to the reactants have been found to be strongly influenced by the nature of the support used. In particular, higher values of the reaction order with respect to propene have been found on Pt/Nylon samples. The presence of electron-deficient sites is suggested. Addition of Sn causes a drastic decrease in catalytic activity, suggesting Sn enrichment on the surface and/or an electronic interaction between the two metal components.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
