Production of bio-jet fuel range hydrocarbons from catalytic HDO of biobased difurfurilydene acetone over Ni/SiO_2-ZrO_2 catalysts

摘要

Biobased difurfurylidene acetone produced by aldol condensation of furfural was used as a renewable feedstock for production of jet fuel range hydrocarbons via the hydrodeoxygenation (HDO) process. The reaction was carried out in a single step at 280 degrees C using Ni/SiO2-ZrO2 (Si/Zr = 1, 3, 5) as catalysts. The influences of Si/Zr ratio as well as Ni content were examined. Excellent results in terms of activity and selectivity towards the formation of bio-jet fuel range hydrocarbons C13-C16 have been obtained. The catalyst's performances were related to the nature and the strength of the support acidity as well as to the metal-support interaction.
