As a carbon-neutral and renewable raw material, cellulose can be transformed into biomass fuels to reduce the dependence on fossil carbon dioxide emissions. In view of harsh reaction conditions, low selectivity product, easy deactivation catalyst, this study studied use photothermal catalytic technology convert bio-oil rich in levulinic acid. It was discovered that synergistic effect between heating photocatalysis is present degradation. Different metals were loaded nanotubes doped with titanium prepare different catalysts, their effects compared. found TiO2-CNT platinum metal exhibited highest performance. By adopting Pt/TiO2-CNT as conversion rate reached 99.44%, LA 44.41% at 220 °C for 3 h. catalysis increased H/C ratio decreased O/C liquid calorific value 21.01 MJ/kg. This promote further industrial application lignocellulose fuel oil decrease environmental pollution caused by massive consumption fuels.
