1. Fuel conversion and ash formation interactions : a thermochemical study on lignocellulosic biomass
Sammanfattning : 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. LÄS MER
Sammanfattning : The goal of the thesis is to evaluate if developed phase chemical process models for cement clinker and lime production processes are reliable to use as predictive tools in understanding the changes when introducing sustainability measures.The thesis describes the development of process simulation models in the application of sustainability measures as well as the evaluation of these models.

3. Fine particle emissions and slag formation in fixed-bed biomass combustion : aspects of fuel engineering
Sammanfattning : There is a consensus worldwide that the share of renewable energy sources should be increased to mitigate climate change. The strive to increase the renewable energy fraction can partly be met by an increased utilization of different biomass feedstocks. LÄS MER
Sammanfattning : This thesis reports the results from an in-depth longitudinal study of how a new strategy actually forms in practice. The focus is on a Swedish multinational firm called the “MECH Group” and its efforts to combine environmental and business concerns in the new strategy called “Positive Impact. LÄS MER
5. Wise Process Routes for Varying Feedstock in Base Metal Extraction : Modelling of a Peirce-Smith Converter and Investigation of Buildup Formation in an Electric Smelting Furnace
Sammanfattning : Copper, like silver and gold, is one of the metals that are known to have been worked by some of the oldest civilisations on record. It is used forits unique properties such as corrosion resistance, good workability, high thermal conductivity and attractive appearance. LÄS MER
