  1. 21. Novel Ammonia Storage Materials for SCR Systems : Carbon Materials – Salt Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nicolas Grimaldos Osorio; [2019]
    Keywords : magnesium chloride; ammonia; carbon materials; SCR; NOx reduction; sorption;

    Abstract : The emissions of nitrogen oxides (NOx) are a serious environmental problem due to its relationship with the formation of smog, acid rain and because they are dangerous for human and animal health. These gases are produced in high quantities in diesel engines used for automotive applications, and different strategies are being used to reduce them, among which are the Selective Catalytic Reduction (SCR) systems.

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

    University essay from KTH/Energiteknik

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

    Abstract : 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. READ MORE

  4. 23. Biomonitoring of soil remediation workers´ exposure to polycyclic aromatic compounds (PACs) – method development and characterisation of PACs in blood

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Julia Jejdling; [2019]
    Keywords : occupational exposure; creosote; contaminated sites; gas chromatography-mass spectrometry GC-MS .;

    Abstract : For a long period of time, it has been common to use creosote for impregnation of railroad ties. Creosote consists of 85% polycyclic aromatic hydrocarbons (PAHs), of which some are carcinogenic and/or mutagenic. READ MORE

  5. 24. Optimization of Pulse Electric Field Treatment and Vacuum Impregnation for Reducing Freezing Injury of Thawed Rucola Leaves

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Imelda Christiana Nyoto; [2018]
    Keywords : food engineering; livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freezing injuries usually take place in thawed plant-based food products. To reduce freezing injuries, Pulse Electric Field (PEF) treatment and Vacuum Impregnation (VI) of cryoprotectant were used before the freezing process. READ MORE

  6. 25. Application of pulsed electric fields and vacuum impregnation to improve the freezing tolerance of fresh Origanum vulgare leaves

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Iliana Karasa; [2018]
    Keywords : Oregano leaves; Freezing; Freezing tolerance; Pretreatments; Vacuum Impregnation; Pulsed electric fields; food engineering; livsmedelsteknik; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : One of most ancient food preservation methods is freezing because there are not caused significant changes the sensory characteristics and nutritional value of foods. Last decade, have been made great steps for the optimization of freezing tolerance of fresh vegetables, fruits and species. READ MORE
