Triwahyono, Sugeng and Abdul Jalil, Aishah and Shamsuddin, Mustaffa and Hamdan, Halimaton (2005) Isomerization of cyclohexane to methylcyclopentane over Pt/sulfate-ZrO2 catalyst. In: 2nd International Conference on Chemical and Bioprocess Engineering in, 8-10 December 2005, Kota Kinabalu, Sabah.
Skeletal isomerization of cyclohexane to methylcyclopentane over Pt/Sulfate-ZrO2 catalyst was studied in a closed recirculation reactor in the temperature range 413-503 K. In the presence of Pt and hydrogen, the stability and activity of catalyst were enhanced markedly due to generation of protonic acid sites acting as a catalytic site for acid-catalyzed reaction and suppression effect in the formation of polymeric material on the surface of catalyst. A high stability and steady state activity of Pt/Sulfate-ZrO2 catalyst was observed for at least 1h with the estimated apparent activation energy of 20.2 kJ/mol. The activity of catalyst declined continuously due to the formation of polymeric materials and reached to zero level within 2 h.
