| Abstract | Deoxygenation of bio-oil by mesoporous silica-alumina (MSAl), Fe-loaded mesoporous silica (MSFe) and Fe-loaded mesoporous silica-alumina (MSAl/Fe) catalysts with different Al and Fe contents was studied. The amount of Al and Fe in the prepared catalysts was 1-10 mol% and 1-10 wt%, respectively. Oil yield after catalytic cracking tests by these catalysts was not significantly low (31.2-52.8 wt%) compared to the oil content of the raw bio-oil (67.3 wt%). Water content (32.7 wt% in raw bio-oil) was remarkably lowered to less than 10 wt% by all catalysts. Moreover, calorific value of raw bio-oil (22.5 MJ kg-1) increased to 30-31.8 MJ kg-1 after cracking. Oxygen content in the produced oil decreased with increasing Al content. Although Fe showed a suppressing effect of deoxygenation, an addition of Fe increased H/C ratio of oil. Deoxygenation by MSAl-10/Fe-10, which is the catalyst with the highest Al and Fe contents, produced an oil with the least oxygen content and relatively high H/C ratio among the studied catalysts. |
