1. Biomass to Biofuel : Syngas Cleaning and Biomass Feedstock
Abstract : This thesis builds around the idea of a biofuel production process that is comprised of biomass production, biomass gasification, gas cleaning, and fuel production. In this work, we specifically looked into H2S removal as a part of cleaning the producer gas and flocculation of microalgae which is involved in the harvesting of microalgae after biomass production.

2. Biomass-fuelled PEM FuelCell systems for small andmedium-sized enterprises
Abstract : Biomass-fuelled proton exchange membrane fuel cells (PEMFCs) offer asolution for replacing fossil fuel for hydrogen production. Through using thebiomass-derived hydrogen as fuel, PEMFCs may become an efficient andsustainable energy system for small and medium-sized enterprises. READ MORE

3. Catalyst Design for the Valorisation of Biomass-derived Furans into Aromatics
Abstract : Anno 2023, mankind must strive towards a more sustainable chemical industry; one that does not solely rely on fossil fuels but also utilises renewable feedstocks such as biomass. Biomass can be catalytically converted into commodity chemicals such as aromatics, through intermediates like furans. READ MORE

4. Turbomachinery in Biofuel Production
Abstract : The aim for this study has been to evaluate the integration potential of turbo-machinery into the production processes of biofuels. The focus has been on bio-fuel produced via biomass gasification; mainly methanol and synthetic natural gas. The research has been divided into two parts; gas and steam turbine applications.

5. Fast pyrolysis of biomass : primary products and reaction pathways
Abstract : Pyrolysis of biomass to produce liquid fuel and chemicals has been considered as an alternativeto fossil fuel because biomass has a lower environmental impact; moreover, it is renewable andcould be sustainable. However, the process of bio-oil production involves a series of complexchemical reactions which are dependent on the biomass feedstock and composition,temperature, heating rate as well as residence time.
