| Abstract | The transition toward the inevitable fossil-fuel-free era is yet to be accomplished by developing directly competing alternatives. Several technologies have a propitious potential to solve global environmental crises such as food waste while producing high-quality oil comparable to that of fossil fuel. Hydrothermal Liquefaction (HTL) is a promising technology that processes wet waste feedstocks into crude-like oil (bio-crude) under subcritical conditions of the water. Bio-crude has lower heating values than fossil fuels due to their high heteroatomic content of oxygen and nitrogen, hence additional upgrading steps are necessary to improve the oil characteristics. Catalysts can play a key role in enhancing the oil quality by altering the reactions pathways during HTL. Heterogeneous catalysts are favoured for industrial application due to their recyclability and reusability, but they appear to be less active than homogenous catalysts due to their suffering from deactivation among other reasons. Nano-catalysts with their physical properties can offer more accessible active sites than conventional catalysts which may potentially lower the deactivation effect.
This study examines the effectiveness of synthesized iron-based nano-catalysts in improving the yield and quality of bio-crude produced via HTL. Several factors were considered such as the type of support, and the presence of other different metal active sites. The quality of bio-crudes produced using the catalysts were evaluated based on their elemental composition, heating values, boiling points distribution fractions and relative content of certain functional groups. Asphaltenes content was also considered as a quality aspect since it is a reason for lowering the value of oil and a source of many troubles during refining operations. |
