Abstract

The effect of adamantane (Ad) has been studied on the activity and selectivity of the H- and Pt/H-forms of zeolite Y and mordenite (MOR) in the hydroisomerization and cracking of n-heptane at 443 K. Ad was found to induce pronounced increase in the isomerization activity and selectivity of the H-Y zeolite, while the activity of the Pt/H-Y and MOR was only moderately influenced. Findings suggest that Ad acts as a hydride transfer cocatalyst, but, its activity is controlled by the limited accessibility of the active sites within the zeolitic channels.
