Abstract
In recent decades, biomass attracted a great deal of attention as an alternative source for fuels and chemicals produced from fossil sources. When aiming for liquid bio-fuels, fast pyrolysis emerges as one of the prominent technologies. Major challenges in direct fast pyrolysis utilization are associated with high content of oxygenated organics in the produced bio-oil with high degree of functionalization. Present thesis applies catalytic hydrodeoxygenation as a promising route to reduce oxygen content in bio-oil by making use of model compounds. This thesis investigates alternative Mo based catalysts with varying catalyst properties to assess their performance during anisole hydrodeoxygenation through kinetic experimentation and material characterization. Through which, different factors affecting catalysts’ activity, stability and deoxygenation selectivity have been studied in detail and valuable insights are gathered. Subsequently, the potential to extrapolate the information obtained on bio-oil model compounds’ hydrodeoxygenation to more complex feedstock is explored using aromatics, aliphatic (C6, C7) carboxylic acids, aldehydes, alcohols and their mixtures. Present thesis lays a good foundation for the extension of knowledge on catalyst and operating conditions requirements for bio-oil catalytic upgrading.
