  1. 1. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristina Arnqvist; [2023]
    Keywords : r-PET; polyester yarn; NIAS; risk assessment;

    Abstract : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. READ MORE

    Author : Joachim Björklund; [2019]
    Keywords : Inorganic Chemistry; Bioinorganic Chemistry; CORM; Photo-CORM; Photosensitizers; Synthesis; Characterization; Oorganisk kemi; Chemistry;

    Abstract : It is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is the fact that it is not trivial to control the volume of gas inhaled, compromising its use as a therapeutic agent. READ MORE

  5. 4. Catalytic Upgrading of Fast Pyrolysis Bio-oil Using Zeolites

    University essay from KTH/Kraft- och värmeteknologi

    Author : Elena Wikberg; [2019]
    Keywords : ;

    Abstract : Fast pyrolysis bio-oil is considered as a possible source for production of liquid bio-fuels and bio-chemicals enabling the necessary transition to a renewable energy system. In this Master’s thesis work the upgrading of fast pyrolysis bio-oils with Fluid Catalytic Cracking (FCC) conversion process at industrially relevant conditions is studied using Fluid Catalytic Cracking Micro Activity Test (FCC MAT) unit at RISE ETC in Piteå, Sweden.
