Methods for deoxygenating treated biomass-derived pyrolysis oil are provided. The treated biomass-derived pyrolysis oil is exposed to a catalyst having a neutral catalyst support such as a non-alumina metal oxide support, a theta alumina support, or both. The non-alumina metal oxide support may be a titanium oxide (TiO2) support, a silicon oxide support, a zirconia oxide (ZrO2) support, a niobium oxide (Nb2O5) support, or a support having a mixture of non-alumina metal oxides. The catalyst may include a noble metal or a Group VIII non-noble metal and a Group VIB non-noble metal on the neutral catalyst support. The treated biomass-derived pyrolysis oil is introduced into a hydroprocessing reactor in the presence of the catalyst under hydroprocessing conditions to produce low oxygen biomass-derived pyrolysis oil.
