26. Developing an Environmentally Friendly Approach for Ash Removal in Hard Carbon Anodes
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Hard carbon is regarded as one of the most promising anode materials for sodium-ion battery. However, the ash content of the hard carbon anode inherited from the precursor have several negative impacts on the electrochemical performance of hard carbon. LÄS MER
27. Techno-economic analysis of a waste-to-energy system using innovative pyrolysis process
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Waste management is of growing concern with increasing amount of municipal waste generation and the industry standards are becoming stricter due to climate goals and sustainable development. Waste-to-energy (WTE) systems in the form of waste incineration have been promoted as a low-carbon energy source, but nevertheless have high greenhouse gas (GHG) emissions. LÄS MER
28. Biokol i substratblandningar : möjlighet för plantskolenäringen att minska användning av torv
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Genom att använda andra typer av material för substratblandningar till odling av träd och buskar i plantskolenäringen kan man minska användningen av torv. I detta självständiga arbete har olika material använts till försök för att se möjligheter till att hitta alternativ till delar i ett, ur växtens synpunkt, bra substrat. LÄS MER
29. Purification of Engineered Graphite for Advanced Application
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Graphite has important applications in several key industries, which has been listed as a “criticalraw material” considered to be supply-risk by European since 2020. Purification of engineered graphite is one of the essential processes for the manufacturing of high-quality graphite. LÄS MER
30. Biochar from separated digestate and pig manure as soil amendment
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and EnvironmentSammanfattning : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. LÄS MER
