Converting ethylene to biojet fuel range hydrocarbons via oligomerization is an important step in biojet production from ethanol. The present study investigates the catalytic ethylene oligomerization over platelet Ni-AlSBA-15 mesoporous catalysts. The catalysts are synthesized and characterized using nitrogen adsorption-desorption isotherms, X-ray fluorescence and X-ray diffraction techniques. The catalytic performances are then evaluated in a continuous flow fixed-bed reactor under various conditions of reaction weight hourly space velocities (0.56-4.5 h −1), temperatures (150-350 °C) and pressures (1-20 bar). Experimental results demonstrate that platelet Ni-AlSBA-15 is a promising catalyst for the ethylene oligomerization to produce biojet fuel range hydrocarbons. It performs a good catalytic activity, yielding 98-99 mol% ethylene conversion and 34-42 wt% C 8+ selectivity at 0.56 h −1 , 275-300 °C and 20 bar. The obtained products contain mainly C 4-C 10 olefins with low aromatic compounds. Moreover, the catalyst exhibits good stability of the activity during long periods of operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
