Catalysts for slurry-phase hydrotreating of bio-oil
(2021)The European Green Deal, a policy initiative set by the European Commission, aims to reduce greenhouse gas (GhG) emissions, and ultimately achieve an economy with net-zero GhG emissions by 2050. Achieving these targets ... -
Characterization of Industrial Filter Materials for Improved Filter Medium Selection
(Åbo Akademi, 2019)Filter fabrics for solid/liquid separation have been analyzed and characterized in order to provide additional knowledge about said fabrics. Three different fabrics, AINO, MITO and ASKO have been studied in this thesis as ... -
Chemical addition to the wet web using foam application
(2022)Foam application is a promising new method for applying papermaking chemicals to wet paper webs. It is based on using aqueous foam as a carrier fluid and has simultaneously improved wet web runnability and furnish strength ... -
Compounding Toolbox for Polypropylene Film Recycling
(2021)The recyclability of materials and plastics in general has been discussed a lot in recent years. The majority of the plastic waste ends up in landfills and is being incinerated for energy. On the other hand, the recycling ... -
Control of the particle size distribution of a cement grinding circuit
(2021)For the past decades, the Blaine value has been the predominant characteristic when controlling the process parameters of a cement grinding circuit. The Blaine method measures the permeability of the cement, and therefore, ... -
Degradation of polydimethylsiloxane in simulated industrial process environments
(2021)Polydimethylsiloxane (PDMS) is commonly used in the Kraft process as an anti-foaming agent, which is added during the pulp-washing stage, where the pulp is separated from the black liquor. Crude tall oil (CTO) is later ... -
Determination of boiling heat transfer coefficients in plate heat exchangers
(Åbo Akademi, 2019)I dagens samhälle växer behovet av kylutrustning ständigt. Kylutrustning kommer man i kontakt med i många olika applikationer så som; kylare i bilar, kylskåp och luftkonditioneringsapparater. Andra ständigt växande marknader ... -
Development of a microfluidic bead-based immunoassay
(2021)The purpose of this Master’s Thesis work was to develop a prototype of a fluidic analysis method based on Wallac Oy’s solid phase, two-site immunometric assay. Immunometric assays are used for detection and quantitation ... -
Development of a novel artificial nose with conductive polymers of 3,4-ethylenedioxythiophene and its functionalised derivatives
