    Sammanfattning : Kemiindustrin har en betydande roll på den globala marknaden och dess produkter hittas i nästan alla tillverkade produkter. Kemiindustrins påverkan på klimatet är stor och sker både genom hanteringen av dess slutprodukter och även i själva produktionen. LÄS MER

  4. 3. Transformer-based Model for Molecular Property Prediction with Self-Supervised Transfer Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Lyu Lin; [2020]
    Nyckelord :Self-supervised Pre-training; Transfer Learning; Molecular Property Prediction; Transformer;

    Sammanfattning : Molecular property prediction has a vast range of applications in the chemical industry. A powerful molecular property prediction model can promote experiments and production processes. The idea behind this degree program lies in the use of transfer learning to predict molecular properties. The project is divided into two parts. LÄS MER

  5. 4. Downscaling and modelling of an ion-exchange chromatography column for purifying glucose solutions

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Viktor Geraldsson; [2020]
    Nyckelord :Ion-exchange; chromatography; glucose; purification; modelling; equilibrium isotherm; Matlab; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : To utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. LÄS MER

  7. 5. Production of volatile fatty acids from anaerobic digestion using food waste, sludge and cow manure

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Zahraa Alshwan; Simon Hultman; [2019]
    Nyckelord :VFAs; anaerobic digestion; food waste; sludge; cow manure;

    Sammanfattning : Volatile fatty acids (VFAs) are important building blocks for the chemical industry. These acids can be produced through environmentally friendly processes from a variety of wastes, such as food waste, sludge and cow manure, through anaerobic digestion (AD). The main objective of this thesis was to investigate which operating parameters (e.g. LÄS MER
