| dc.description.abstract | The catalytic upgrading of light crudes is a very important aspect of the petrochemical industry. In recent years, the desulfurization of marine fuels and the deoxygenation of biofuels attract more attention due to the implementation of IMO 2020 sulfur emission regulation and the increased demand for renewable fuels. In this thesis, the catalytic desulfurization of marine gas oil and marine diesel oil, as well as the catalytic deoxygenation of vegetable oil are both conducted under a methane environment, and using various catalyst supports doped with several metal species. Besides, some control experiments are also conducted under a nitrogen environment while the other reaction conditions remain the same. This research aims at fine performances of reducing sulfur and oxygen content within the light oils and oil quality improvement while yielding coke at a low level through methane-assisted catalysis. Catalysts are screened to gauge those with the best performances. As a result, the methane-assisted desulfurization and deoxygenation techniques are proved to be feasible and achieve promising performances of sulfur or oxygen content removal. The participation of methane during the upgrading processes not only promotes the desulfurization and deoxygenation performances but also improves the quality of the product oils, and reduces coke yields. | en_US |
