摘要：
Nano-crystalline (about 44 nm in size) zeolite beta was hydrothermally synthesized. Effects of reaction temperature, pressure, hydrogen/n-hexane molar ratio, platinum content of the catalyst, and contact time on n-hexane conversion and selectivity to desired branched-paraffins were studied. At conditions affording the highest yields of branched paraffins, the catalyst did not show any sign of deactivation for 20 h onstream. Performance of Pt, Pd, Ni and Pt C Pd impregnated zeolites was compared. It could be concluded that higher conversions and selectivities may be attributable to the size of the crystals of zeolite beta employed.
