  1. 1. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Cecilia Zambelli; [2023]
    Keywords : ;

    Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

  3. 2. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Harry Tibbetts; [2023]
    Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

  4. 3. Techno-economic evaluation of hydrochar via hydrothermal carbonisation of organicresidues

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

    Author : Abdirahman Abdullahi; [2022]
    Keywords : Technoeconomic analysis; energy system modelling; HTC; hyrochar; system integration; OSMET;

    Abstract : This thesis has investigated the techno-economic feasibility of upgrading the sludge from a chemical pulp mill to hydrochar via hydrothermal carbonization (HTC). The intended use of the hydrochar was to replace fossil coal within metallurgical applications in the iron and steel industry. READ MORE

  5. 4. 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

  6. 5. Large Surface Area of Graphene with Controlled Interlayer Spacing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)
