Abstract [en]

This master thesis project has, on behalf of Cortus Energy AB, investigated how to increase the

suitability of so called low value fuels for use in the thermochemical conversion process WoodRoll®.

The theoretical background of the report includes theory on pyrolysis, gasification and ash chemistry,

as well as a description of WoodRoll® and a comparison between Woodroll® and more conventional

technologies. A theoretical and an experimental trial have been conducted to investigate methods

for potentially increasing the ash fusion temperatures of low value fuels. The theoretical study

compared published articles on leaching and co-gasification. The experimental study was performed

using thermogravimetric analysis and investigated if blending was a viable alternative for improving

behavior. Three new types of industrial wastes were also tested.

Both the theoretically investigated pretreatment methods and the blending were indicated to

improve the behavior of low value fuels. When compared, blending was deemed to be economically

favorable over the investigated pretreatment methods. The most economically favorable alternative

is if two low value fuels with complementing characteristics can be successfully blended. Blending

would also be easier to integrate with the current WoodRoll® process design and showed promise of

high fuel flexibility. The behavior of the blends were influenced by their level of homogeneousness,

a relationship of interest to investigate further in the future.
