摘要：
The magnetic properties of Pt-RE (RE ≡ Gd, Tb, Dy, Ho, Tm) catalysts supported on γ-Al2O3 were studied using a Faraday magnetic balance. The conversion of cyclohexane, n-hexane and n-heptane on these catalysts has been investigated using a pulsed catalytic flow microreactor. The results show that heavy rare earths can improve the activity, stability and magnetic properties of platinum re-forming catalysts. The relationship between the adsorption and magnetic susceptibility of Pt-Gd/γ-Al2O3 catalysts was also investigated under different conditions.
