Abstract

The effect of platinum and reaction temperature was investigated in the conversion of methylcyclopentane (MCP) with hydrogen at atmospheric pressure. The dispersed 0,5wt% Pt on AlPO4 (PtAlP), and Mo/AlPO4 (PtMoAlP) metal catalysts were prepared by incipient wetness impregnation or co-impregnation methods. The most active catalyst in the conversion of MCP was PtAlP and the most selective to MCP ring opening was PtMoAlP. High temperature promoted ring opening at the secondary–tertiary positions, which was attributed to the adlineation sites. At low temperatures, PtMoAlP promoted only the ring enlargement reaction while PtAlP promoted both ring opening and ring enlargement. Ring enlargement of MCP to cyclohexane and benzene was catalysed by electron deficient adduct sites, while ring opening to 2-meythylpentane (2-MP), 3methylpentane (3-MP) and n-hexane (n-H) was catalysed by metallic sites. At high temperatures, MCP broken into C1–C5 fragments and deactivation of the catalysts was observed.
