dc.description.abstract
In this paper, a study on the hydrogenation of carvone by using Pt/Al2O3, PtSn/Al2O3, PtGe/Al2O3, Pt/C and PtSn/C is reported. TPR, H2 chemisorption, XPS and test reaction results show that the addition of a second metal to Pt leads to important modifications of the structure of the metallic phase, though these modifications are different according to the nature of the support (Al2O3 or C). The activity and selectivity of these catalysts in carvone hydrogenation depend not only on the composition of the metallic phase, but also on the nature of the support. Thus, adding Sn or Ge to Pt/Al2O3 enhances the selectivity to unsaturated ketones (at a fixed carvone conversion, Xcarv = 1). When Pt is supported on activated carbon, small amounts of unsaturated alcohols are observed. The Sn addition to Pt/C sharply enhances the selectivity to carveol formation (the doubly unsaturated alcohol) reaching values close to 100% at the initial stages of the reaction. © 2001 Elsevier Science B.V.
