1. Biochemical conversion of biomass to biofuels pretreatment–detoxification–hydrolysis–fermentation
University dissertation from Umeå : Umeå universitetAbstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE

2. Biofuels from Kraft Black Liquor Pilot-Scale Gasification Development and Techno-Economic Evaluation of Industrially Relevant Biofuel Production Pathways
University dissertation from Luleå University of TechnologyAbstract : Fuel combustion for transport was responsible for 24% of EU-28 greenhouse gas (GHG) emissions in 2016. Member states are expected to ensure that the share of renewable energy in the transport sector is at least 14% by 2030. Some countries, such as Sweden, have more ambitious targets. READ MORE

3. Benefits of Integrated Upgrading of Biofuels in Biorefineries - Systems Analysis
University dissertation from Luleå University of TechnologyAbstract : As a result of increasing concerns about climate change, there is considerable current interest in increasing use of CO2-neutral biofuel in the energy system. Increased use of biomass fuel requires that it be upgraded in order to facilitate transportation and distribution to end-users. READ MORE

4. Energy Efficient Processes for the Production of Gaseous Biofuels - Reforming and Gas Upgrading
University dissertation from Department of Chemical Engineering, Lund UniversityAbstract : Replacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. READ MORE

5. Becoming Biofuels. The messy assembling of resources, sustainability, poverty, land use, and nation-states
University dissertation from Department of Chemical Engineering, Lund UniversityAbstract : Biofuels have come to represent the will to mitigate climate change by replacing fossil fuels with so-called climate-friendly and renewable plant sources, and to improve rural and poor conditions in the South through biofuel crop production, farm job creation, and smallholder cash cropping. The expansion of biofuels in countries in the South largely pivoted upon ‘the will to develop’, specifically through the oil shrub Jatropha curcas L. READ MORE
