6. Hydrodeoxygenation (HDO) catalysts Characterization, reaction and deactivation studies
Abstract : Production of biomass derived fuels such as renewable diesel, are primarily intended to reduce the reliance of the conventional engines on petroleum fuels as well as the emission of CO2 from fossil hydrocarbons. Hydrodeoxygenation (HDO) is a powerful technique that has been regularly used in the fuel upgrading processes. READ MORE

7. Excess heat utilisation in oil refineries - CCS and algae-based biofuels
Abstract : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. READ MORE

8. Experimental evaluation of renewable drop-in fuel blends for compression ignition engines
Abstract : Driven by the need to reduce greenhouse gas emissions while meeting the growing demand for mobility, the transport sector is shifting towards more sustainable and less polluting energy sources. Although vehicle electrification is advancing, it will take decades for electric vehicles to completely replace all current vehicles powered by internal combustion engines. READ MORE

9. Food or fuel? : trade-offs between food and biofuels globally and in small-scale organic agriculture
Abstract : There are great expectations on agriculture to provide both food and fuels in the future. Previous attempts to estimate the global bioenergy potential have produced varying results, indicating major uncertainty. This thesis investigated the global theoretical 'potential', or limit, for biofuels based on current agricultural systems. READ MORE

10. Characteristics of Particulate Emissions from Low Temperature Combustion and Renewable Fuels : Aerosol Mass Spectrometry of Refractory Carbonaceous Particles
Abstract : Particulate air pollution is one of the major causes of premature death in the world, and combustion-derived soot emissions contribute strongly to the particulate pollution to which humans are exposed. Black carbon (BC) is one such emission and denotes soot with strong light absorption in the ultraviolet to infrared spectrum. READ MORE
