Abstract
Conversion of lignocellulosic biomass into the transportation fuel is an attractive concept [1]. Using ex
situ Catalytic Fast Pyrolysis (CFP) improves to upgrade bio-oils via catalytic deoxygenation of the
biomass pyrolysis vapors. Zeolites are often used in this technique as the catalyst; however, in order to
reduce minimum fuel selling price and improve carbon yields, ongoing research emphasizes catalyst
optimization [2]. By using bifunctional metal-acid catalysts and utilizing hydrogen, it is possible to
improve carbon yields by minimizing the carbon-containing light gasses (since oxygen is removed as
water) and by reducing coke formation. Current research and development activities focuses on
Pt/TiO2catalysts as the most promising catalyst candidates for the hydrodeoxygenation process. The aim
of this research is to determine the structure-function relationships of the Pt/TiO2 catalyst and the role of
Pt dispersions within the catalyst on performance, using operando scanning transmission electron
microscopy (S/TEM).
