CATALYTIC ACTIVITY OF THE LANTHANIDE OXIDES FOR THE DEHYDROGENATION OF CYCLOHEXANE
Journal Article
·
· Journal of Physical Chemistry
A rising temperature flow reactor was used to determine the activation energies, frequency factors and kinetics for the heterogeneous dehydrogenation of cyclohexane over La₂O₃, CeO₂, Pr₂O₃, Nd₂O₃, and Sm₂O₃. The effect of crystal structure was evaluated by preparing the oxides in their different crystal forms (A, B, or C structures) and the effect of a support was investigated by depositing the oxides on alumina. Within the error of experiment, no effect of the support, crystal structure, paramagnetism or valence state could be detected, indicating perhaps that the catalytic activity of the lanthanide oxides is associated with outer electronic states.
