| dc.description.abstract | The world is accelerating towards a gasoline fuel-free future and research focus is shifting towards alternative energy. The efficient use of remaining downstream fossil-fuel derived oil sources and effective treatment of renewable fuel sources has become imperative. Remaining fossil fuel sources like crude oil distillation and Fischer Tropsch products, which contain large amounts of n-paraffins, are no longer desirable as fuels because of their negative environmental impact. As such, they need to be valorized to valuable chemicals instead. This issue is addressed in this thesis by a thorough investigation of numerous hydrocarbons which can be found in such sources, including olefins, paraffins, and naphthenes. Their valorization to aromatics by heterogenous catalysis are investigated to provide a solution and use for remaining hydrocarbons derived from fossil fuels. Additionally, this thesis focuses on the treatment of bio-oils, a suitable fuel source replacement for fossil fuel-based fuels. Bio-oils can come from various sources, but they all have the same issue; they are high in oxygen content. This means energy density is low, acidity is high, and that the oil is thermochemically unstable. Hydrotreating is currently used to deoxygenate these feedstocks as it contributes to decarbonylation, decarboxylation, and saturation reactions. However, hydrogen is expensive, unavailable naturally, and environmentally unfriendly to synthesize as it is obtained predominantly from steam methane reforming. Direct use of methane for the deoxygenation of bio-oils (methanotreating) is investigated in this research. With carefully tailored catalysts, methane can be activated at low temperatures and pressures to provide hydrogen directly and contribute its carbon moiety to oxygen containing components in the product, highlighting the potential for methanotreating in the future of renewable fuels. | |
