Forming bio-oil from wood is a strategy to develop fuel from biomass, however, the oxygen content of bio-oil (40%) means that the energy density is not as high as crude oil. It is also too unstable to store. So, giving bio-oil an upgrade, decreasing its oxygen content and reactivity, is necessary.
Scientists from Germany have used Raney Ni as a catalyst and propan-2-ol as a H-donor to upgrade phenolics and aromatics from biorefinery feeds. The team demonstrated that hydrogen transfer reactions could be carried out under low-severity conditions. Current methods require extreme conditions and give low yields.
