Bio-oil produced from Japanese cedar was deoxygenated by catalyst under H_2 atmosphere. In a single stage upgrading using mesoporous silica-alumina (MSAl), deoxygenation ratio was higher than that of Ni-loaded ZSM-5 (ZSM-5/Ni). This result suggests hydrodeoxygenation by nickel was restricted because the pore size of ZSM-5 is much smaller than that of MSAl. However, toluene, benzene and naphthalene were more obtained when ZSM-5/Ni was used. In a two stage upgrading using MSAl and ZSM-5/Ni, deoxygenation ratio increased compared to the single stage upgrading, suggesting that MSAl and ZSM-5/Ni catalysts play roles of decomposition of bio-oil and hydrodeoxygenation, respectively.
