Development of Ni/Al-KIT-6 catalyst for ethylene oligomerization to jet fuel range hydrocarbon

Oligomerization of ethylene using nickel supported on an acidic Ni-AlKIT-6 catalyst in a laboratory-scale packed bed reactor for the synthesis of jet fuel. We evaluated the effect of Si/Al and %Ni loading on supported Ni-AlKIT-6 oligomerization catalysts were prepared by post-synthesis alumination of KIT-6 silica with sodium aluminate, followed by impregnation with nickel. Characterization techniques, including powder X-ray diffraction, X-ray fluorescence (XRF), BET surface area analyzer proved the perfect pore system of the KIT-6 materials, with aluminum tetrahedrally mainly coordinated in the silica framework. Ni-AlKIT-6 exhibited catalytic behavior in the oligomerization reaction for ethylene give to jet fuel(C8+). On the other hand, the higher density and strength of the Brønsted acid sites. The Ni/Al-KIT-6 exhibited good catalytic performance in the oligomerization reaction to produce the jet fuel(C8+).
