  1. 1. En studie i vattenrening med elektrokoagulation : Koaguleringsförmågan hos utvalda föreningar

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Axel Wieslander Jansson; [2019]
    Nyckelord :vattenrening; elektrokemi; elektrokoagulation; organiska föreningar;

    Sammanfattning : Vatten- och energiförbrukning är ett av mänsklighetens största nuvarande och framtida problem då världens vattenkonsumtion ständigt ökar på grund av bättre levnadsstandard samt ständigt ökande population och industrialisering. Förorenat vatten orsakar sjukdomar, sänkt livstid, reducerad sanitet och försämrad hälsa. LÄS MER

  2. 2. Influence of Nucleation Techniques on the Degree of Supercooling and Duration of Crystallization for Sugar Alcohol as Phase Change Material : Investigation on erythritol-based additiveenhanced Composites

    Master-uppsats, KTH/Energiteknik; KTH/Energiteknik

    Författare :JiaCheng Lin; HaoRan Teng; [2019]
    Nyckelord :Phase Change Material; Latent Thermal Energy Storage; Temperature-history; Sugar Alcohols; Supercooling; Duration of crystallization; Crystallization; Solidification; Fasändringsmaterial; Latent Termisk Energilagring; T-history; Sockeralkoholer; Underkylning; Varaktighet av kristallisering; Kristallisering; Stelning;

    Sammanfattning : Utilizing Phase Change Materials (PCM) for Latent Thermal Energy Storage (LTES) applications have previously been extensively researched as a measure to reduce greenhouse gas emissions from energy consumption. In order to make use of the waste heat from industrial processes for LTES purposes, a new demand emerged for PCMs capable of phase change in mid-temperature ranges of 100 °C - 200 °C. LÄS MER

  4. 4. Study of high flash point ethyl alcohol-based secondary fluids applied in Ground Source Heat Pumps systems

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Luis Enrique Carrion Domenech; [2019]
    Nyckelord :indirect refrigeration system; secondary fluid; flammability; alcohols; geothermal heat pump systems; properties.;

    Sammanfattning : Ethyl alcohol (ethanol) as secondary fluids is very popular as heat transfer fluid for indirect refrigeration system with ground source heat pump systems (GSHP) in several countries such as Sweden, Norway, Switzerland, Finland and other European countries. There have been several researches about the future ofthe refrigeration sector, refrigerants and refrigeration systems. LÄS MER

  5. 5. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER
