“…Lignocellulosic bio-oils contain the degradation products of biomass (cellulose, hemicellulose and lignin [4]) and are made up of a mixture of different organic compounds [5] with different chemical compositions depending on the pyrolysis step [6]. These bio-oils are promising source for liquid bio-fuels [4,7,8].…”

“…These bio-oils are promising source for liquid bio-fuels [4,7,8]. However, some of the properties of these liquids (elevated viscosity, high O/C ratio, large H 2 O content and low pH) hider their direct use as liquid biofuels [9].…”

“…However, some of the properties of these liquids (elevated viscosity, high O/C ratio, large H 2 O content and low pH) hider their direct use as liquid biofuels [9]. This scenario makes the upgrading of bio-oil an essential challenge in order to obtain liquid biofuels from biomass and several processes such as hydrotreating, hydrocracking and the use of supercritical water [4,7,8,10] have been developed and tested to achieve this goal.…”

“…This latter indicates that more insight should be gained for the scale-up and commercialisation of this emerging technology. Specifically, Penninger and Rep [12] analysed the supercritical water reforming of bio-oil for H 2 production, while Onwudili and Williams [13] studied the supercritical water gasification for the production of CH 4 . Remón et al [10] investigated the use of water in sub-and supercritical state for bio-oil valorisation using a Ni catalyst supported on alumina prepared by coprecipitation (Ni-Co/Al-Mg).…”

This work addresses the preparation, characterisation and screening of different Ni-Co catalysts supported on carbon nanofibres (CNFs) for use in the upgrading of bio-oil in supercritical water. The aim is to improve the physicochemical properties of bio-oil so that it can be used as a fuel. The CNFs were firstly oxidised in HNO 3 and afterwards subjected to a thermal treatment to selectively modify their surface chemistry prior to the incorporation of the metal active phase (Ni-Co). The CNFs and the supported catalysts were thoroughly characterised by several techniques, which allowed a relationship to be established between the catalyst properties and the upgrading results.The use of Ni-Co/CNFs for bio-oil upgrading in supercritical water (SCW) significantly improved the properties of the original feedstock. In addition, the thermal treatment to which the fibres were subjected exerted a significant influence on their catalyticproperties. An increase in the severity of the thermal treatment led to a substantial reduction in the oxygen content of the CNFs, mainly due to the removal of the less 2 stable oxygen surface groups, which allowed their surface polarity to decrease. This decrease resulted in less formation of solid products. However, it also reduced the H/C and increased the O/C ratios of the upgraded liquid. Therefore, a compromise between the yield and the properties of the upgraded bio-oil was achieved with a Ni-Co supported on a CNF with a moderate amount of oxygen surface groups.
