Biomass Technology Group, Colosseum 11, 7521 PV Enschede, 21, The NetherlandsE-mail: yakovlev@catalysis.ruThe consumption of petroleum has surged during the 20 th century, at least partiallybecause of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and naturalgas provide more than three quarters of the world’s energy. On the other hand biomass canserve as a source for both energy and motor fuels, and being renewable it is the onlysustainable source of energy and hydrocarbons for industry and automobile society. Atpresent the alternate fuels are bioethanol and biodiesel only. The bio-oil, which is a product offlash pyrolysis of grinded wood, is another perspective feedstock for the petrol production.However these bio-liquids cannot substitute traditional gasoline and diesel in the internalcombustionengines on its own owing to their lower operational properties. The main reasonis the high oxygen content in above mentioned bio-fuels. Bioethanol and biodiesel can beused as the additive to gasoline and diesel correspondingly while bio-oil requires catalyticelimination of oxygen from it and simultaneous saturation by hydrogen.It should be pointed out that one cannot use traditional hydrocracking catalysts for oilrefineryat hydrotreatment of bio-fuels because of low sulfur content in original feedstock.The main reason of these phenomena is reduction of the sulfided Co- or Ni- containing activecenter to the metal state, followed by coke formation and the catalyst deactivation. When so,sulfur is removed from the catalysts and the target products are contaminated by sulfur. Thus,the objective of the present investigation is to develop non-sulfided catalysts for upgradedbio-fuels production. In the work we have used not only bio-oil (BTG Company) and modelbio-oil compounds but also biodiesel and vegetable oils as the initial feedstock for theupgrading. The obtained upgraded products can be used as improving additives to gasolineand diesel. As a whole developing processes of upgraded bio-fuels production are shown onScheme 1.167
