The model compound of 2-furyl methyl ketone (2-FMK) a product of pyrolysis oil from Saccharina japonnica was used for hydrodeoxygenation (HDO) using ferrous catalyst prepared by incipient wetness impregnation method supported on γ-Al2O3. The effect of metal loading, reaction temperatures, calcination temperatures and phosphorous addition on catalyst activity and stability were investigated. Catalyst activity increased with increasing calcination temperatures and reaction temperatures, however, activity increased with decreasing metal loading. 5 wt% Fe/γ-Al2O3 with high surface area, showed the highest conversion and yield (92.60% and 79.34%), respectively at calcination temperature of 600°C at 400°C. Phosphorous addition to ferrous catalyst showed increase in activity with increasing reaction time and calcination temperature.

The model compound of 2-furyl methyl ketone (2-FMK) a product of pyrolysis oil from Saccharina japonnica was used for hydrodeoxygenation (HDO) using spray-pyrolysis (S.P) prepared catalysts (Ni, Co and CoP) and incipient-wetness impregnation (I.W) prepared catalysts (Ni), supported on γ-Al2O3. The effect of catalyst activity and stability on 2-FMK at different reaction temperatures and calcination temperatures were investigated. Catalyst activity increased with increase in calcination temperature, but decreased with increase in reaction time, for all catalysts. The spray-pyrolysis prepared catalyst Ni/γ-Al2O3-S.P (Ni-loading of 10 wt%, calcinated at 800°C) showed the best activity with 83.02% in 2-FMK conversion at 400°C. The produced gas and liquid was analyzed by gas chromatography (GC) with TCD/FID detector and GC-MS, respectively, to determine the product compositions.

<P><B>Abstract</B></P> <P>We report the hydrodeoxygenation of 2-furyl methyl ketone over iron phosphide catalyst to reform the C<SUB>6</SUB> structure into C<SUB>7</SUB> compounds with higher octane ratings. High conversion and yield were achievable from the reaction at 400°C when 5wt% Fe<SUB>2</SUB>P/γ-Al<SUB>2</SUB>O<SUB>3</SUB> catalyst calcined at 600°C was used. High calcination temperature and reaction temperature are the favorable conditions to achieve high conversion in the reaction. The highest conversion of 92.60% was achieved with 2-allyl furan yield of 79.34% and methyl cylcohexane yield of 13.26% in the liquid phase and 100% carbon dioxide in the gas phase.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Fe<SUB>2</SUB>P/γ-Al<SUB>2</SUB>O<SUB>3</SUB> and Ni<SUB>2</SUB>P/γ-Al<SUB>2</SUB>O<SUB>3</SUB> catalyzed the hydrodeoxygenation of 2-furyl methyl ketone (FMK). </LI> <LI> Effects of reaction temperature, phosphorous, and metal loading were investigated. </LI> <LI> Phosphide catalyst with iron content produced the predominant selectivity of 2-allyl furan and the least methyl cyclohexane. </LI> <LI> 5wt% Fe<SUB>2</SUB>P/γ-Al<SUB>2</SUB>O<SUB>3</SUB> calcined at 600°C had the highest FMK conversion and yield to 2-allyl furan. </LI> </UL> </P>
