1. Biomass conversion through syngas-based biorefineries : thermochemical process integration opportunities
Abstract : The replacement of fossil resources through renewable alternatives is one way to mitigate global climate change. Biomass is the only renewable source of carbon available for replacing oil as a refining feedstock. Therefore, it needs to be utilized not just as a fuel but for both biochemical and thermochemical conversion through biorefining. READ MORE

2. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Abstract : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. READ MORE

4. Alkali Metals and Tar in Biomass Thermochemical Conversion: Development and Application of Online Measurement Techniques
Abstract : Biomass is a renewable resource that can substitute the fossil-based products we depend on today. However, the conversion techniques require further improvement in order to be competitive with the traditional industry. READ MORE

5. Principles and Models of Solid Fuel Combustion
Abstract : Combustion of solid fuels stands for a substantial part of the heat and power production in the world. In this thesis different aspects related to the thermochemical conversion of solid fuels in fluidized and fixed beds are treated, such as: the combustion temperature of a fuel particle related to the surrounding temperature in a fluidized bed combustor (FBC); the fuel loading in a FBC; a transient description of the conversion of non-spherical fuel particles; the thermochemical properties and composition of volatiles released from wood; the thermal conductivity of wood during different stages of conversion; the modelling of a grate furnace; the general combustion behaviour of a fixed bed on a reciprocating or a travelling grate; and finally, the design and construction of experimental units for investigation of combustion in a fixed bed.
