摘要

The activity of medium and large pore zeolites, Y, beta, ZSM-22 and ferrierite was compared in n-hexene skeletal isomerization. Zeolite structure determined the activity, selectivity and stability of the catalyst. Ferrierite performed best in the n-hexene isomerization, while Y-zeolites exhibited the lowest activity. Surprisingly, the amount of acid sites played a minor role in the reaction. However, the zeolites with the highest acid site strength were the most active, also within the zeolite type. The selectivity to isohexene with beta- and Y-zeolite increased with decreasing conversion. More dimerized products were formed on beta-and Y-zeolites than on ferrierite and ZSM-22. The carbon contents of used catalysts increased with increasing micropore area of the zeolite.
