Advancing Bioenergy in Europe: Exploring bioenergy systems and socio-political issues
This thesis concentrates on bioenergy (or biomass utilised for heat, electricity and fuels for transport) as a renewable energy with significant potentials and options. Biomass can be considered as 'stored' solar energy because the process of photosynthesis 'captures' energy from the sun in growing …

Modeling of Bioenergy Production
In this dissertation we address three different sustainability concepts: [1] modeling of biodiesel production via heterogeneous catalysis, [2] life cycle analysis for pyrolysis of switchgrass for using in power plant, and [3] modeling of pyrolysis of biomass. Thus we deal with Specific Aim 1, 2 and …

Soil carbon and nitrogen cycle modeling for bioenergy crops
Due to the increase in the demands for bioenergy, considerable areas in the Midwestern United States (US) could be converted into croplands for second generation bioenergy, such as the cultivation of miscanthus and switchgrass. Study on the effect of the expansion of these crops on soil carbon and …
