1. Opportunities and uncertainties in the early stages of development of CO2 capture and storage
Sammanfattning : The topic of this thesis is carbon dioxide (CO2) capture and storage (CCS), which is a technology that is currently being promoted by industries, scientists and governments, among others, in order to mitigate climate change despite a continued use of fossil fuels. Because of the complex nature of CCS and the risks it entails, it is controversial. LÄS MER
2. Impacts of alternative combustion diluents and hydrogen addition on a swirl-stabilized flame related to gas turbine application
Sammanfattning : The global energy tendency leads to increasing attention on clean combustion technologies in order to eliminate adverse impacts on the environment. The utilization of oxyfuel combustion (CO2 acts as the only combustion dilution), flame diluents, and hydrogen fuel in gas turbine combustion provides a promising solution to reduce combustion pollutant emissions.

3. Sustainability measures in quicklime and cement clinker production
Sammanfattning : This thesis investigates sustainability measures for quicklime and cement clinker production. It is the aim of this thesis to contribute to the effort of creating a more sustainable modus of industrial production. LÄS MER
4. Fast devolatilization of biomass : An experimental study using high-speed imaging, relevant for suspension firing technologies
Sammanfattning : We have performed experiments using imaging techniques in a flame-assisted, drop-tube reactor with optical access, to extract information relevant to the improvement of multi-particle devolatilization models. These models could be of interest for different suspension firing techniques, such as entrained flow biomass gasification, (EFBG) and oxyfuel combustion. LÄS MER
5. Carbon Recovery in A Dual Fluidized Bed Gasifier
Sammanfattning : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. LÄS MER
