Abstract

Abstract

A Ni-Pt bimetal catalyst (Ni-Pt/γ-Al₂O₃) supported on self-synthesized γ-Al₂O₃ nano-film with a surface area of 349 m²/g was prepared via conventional impregnation method. The catalyst was characterized by BET, XRD, SEM and TEM and its performance in methylcyclohexane (MCH) dehydrogenation was evaluated in a fixed-bed microreactor connecting with a gas chromatograph. The results showed that under 350℃ and a volume gas space velocity of 252 h^-1, the conversion of MCH over the 20%Ni-0.5%Pt/γ-Al₂O₃ catalyst reaches 96.99% and the selectivity to toluene approaches 100%.
