  2. 1. Heterogeneously Catalyzed Valorization of Monoterpenes to High Value-Added Chemicals

    Author : Mikhail Golets; Jyri-Pekka Mikkola; Evgenii Rebrov; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalysis; terpenes; alpha-pinene;

    Abstract : A potential industrial process is profitable only if it is successfully implemented by the continuously developing chemical industry. Throughout last decades heterogeneous catalysis has opened doors to the creation of various know-how products which previously were considered unfeasible. READ MORE

    Author : Majid Mustafa; Mats Tysklind; Daniel Ragnvaldsson; Lars Lövgren; Santiago Esplugas; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electro-peroxone; ozone; hydroxyl radicals; advanced oxidation processes; pharmaceuticals; QSAR; biocides; wastewater; removal; predictions; water matrix; activated carbon; sorption; regeneration; environmental science; miljövetenskap;

    Abstract : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. READ MORE

  5. 3. Facilitating electron transfer in bioelectrocatalytic systems

    Author : Alina Sekretaryova; Mats Eriksson; Mikhail Vagin; Anthony Turner; Evgeny Katz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Bioelectrocatalytic systems are based on biological entities, such as enzymes, whole cells, parts of cells or tissues, which catalyse electrochemical processes that involve the interaction between chemical change and electrical energy. In all cases, biocatalysis is implemented by enzymes, isolated or residing inside cells or part of cells. READ MORE

  6. 4. Computer-aided optimization of complex processes in production systems and urban environments

    Author : Mikael Yamanee-Nolin; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; modeling; simulation; complex processes; process systems engineering; preparative chromatography; blue-green systems;

    Abstract : Complex processes can be seen as a series of actions, changes, and/or events that are related in different temporospatial manners, and thus are potentially difficult to understand. Optimizing such a process is therefore not necessarily a simple feat, and doing it experimentally may become both time-consuming and expensive. READ MORE

  7. 5. Catalytic Steam Pyrolysis of Biomass for Production of Liquid Feedstock

    Author : Efthymios Kantarelis; Weihong Yang; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Catalytic Cracking; Catalytic Upgrading; Biomass to Liquids; Bio-fuels; Πυρόλυση; Καταλυτική διάσπαση; Καταλυτική αναβάθμιση; Biomass to Liquids; Βιοκαύσιμα; Pyrolys; Katalytisk Krackning; Katalytisk uppgradering; Biomass to Liquids; biobränslen; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The current societal needs for fuels and chemical commodities strongly depend on fossil resources. This dependence can lead to economic instabilities, political problems and insecurity of supplies. READ MORE
