1. 1. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

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

   Author : Elias Aretorn; [2023]
   Keywords : CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

   Abstract : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. READ MORE

3. 2. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Simon Fridolfsson; [2022]
   Keywords : HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

   Abstract : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. READ MORE

4. 3. ENVIRONMENTAL RADIOLOGICAL STUDIES OF KVARNTORPSHÖGEN Dose and Radiological Risk Assessments for Humans and Biota

   University essay from

   Author : Felicia Hultqvist; [2021-04-06]
   Keywords : Medical physics; NORM; TENORM; Shale ash; Uranium; Polonium; Radiological risk; Humans; Biota;

   Abstract : Background: The pile Kvarntorpshögen and the lakes Surpölen and Norrtorpssjön are the remains of an industry which mined and processed oil shales to extract oil during World War II. The pile mainly consists of shale ash, a waste from the production, while the lakes are nowadays water-filled mining pits. READ MORE

5. 4. Design & optimization of modular tanksystems for vehicle wash facilities

   University essay from Karlstads universitet

   Author : Pontus Marco; [2020]
   Keywords : Water reclamation system; Water treatment; Washing system; Modular; Tank system; Fluid flow; Microsoft Excel; Visual Basic for Applications;

   Abstract : Clean and safe water is important for the well being of all organisms on earth. Therefore, it is important to reduce harmful emissions from industrial processes that use water in different ways. In vehicle washing processes, water is used in high-pressure processes, as a medium for detergents, and for rinsing of vehicles. READ MORE

6. 5. Mechanism of Formation of Soft Particles in Biodiesel Fuel Blends

   University essay from KTH/Materialvetenskap

   Author : Roberta Maria Fiorenza; [2020]
   Keywords : ;

   Abstract : The large environmental impact related to the use of fossil fuel has driven the shift toward renewable sourced alternatives. Fossil diesel can be nowadays replaced by biodiesel, obtained from vegetable oils and fats, mostly used as biodiesel blends. READ MORE
