  1. 21. Improvement of Pt-based catalyst supported on CeZrO2 used for the high-temperature water-gas shift reaction

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Milda Grikainyte; [2022]
    Nyckelord :Water-gas shift; catalyst; chemical engineering; Chemistry;

    Sammanfattning : The iron-chromium (Fe/Cr) catalyst is used for high-temperature water-gas shift (HT WGS) reaction. A major concern using the Fe/Cr catalyst is that it contains hexavalent chromium (Cr+6) which is a potent carcinogen causing health and environmental issues. LÄS MER

  3. 22. Simulation of carbon- monoxide rich syngas through gasification and co-gasification of biomass.

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Musasa Kayiba Tracy; [2022]
    Nyckelord :Gasification; biomass;

    Sammanfattning : Syngas is an interesting energy source for metallurgical processes, as an energy carrier syngas is an efficient way of utilizing the energy in biomass. Utilizing syngas in fuming processes as a carbon source instead of coal was an approach to minimize carbon dioxide emissions produced in the fuming process. LÄS MER

  4. 23. Analysis of Aircraft Emissions Based on Flight Trajectory : ATR 72-500 trajectory and emission study

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Gustav Forsberg; Carl-Michael Sundberg; [2022]
    Nyckelord :trajectory; emissions; Boeing Fuel Flow;

    Sammanfattning : Emissions related to aviation have during the last decades become an important topic of discussion. Besides carbon dioxide ($CO_2$) which is the major pollutant from air travel, other gas emissions such as hydrocarbons ($HC$), nitrogen oxides ($NO_x$), carbon monoxide ($CO$) and sulfur oxides ($SO_x$) also need to be investigated.

  5. 24. Converting an Automobile Engine to an Aircraft Engine

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Gabriel Kronberg; [2022]
    Nyckelord :Piston Engine; Tiny Friendly Giant; Aviation Emissions; Engine Cooling; GREET; BFFM2; Sustainable Aviation Fuel; Engine Conversion; Emission Estimation; Trade Study; Kolvmotor; Tiny Friendly Giant; Flygutsläpp; Motorkylning; GREET; BFFM2; Hållbart flygbränsle; Motorkonvertering; Utsläppsupskattning; Paramterstudie;

    Sammanfattning : This project evaluates the opportunity to convert a three-cylinder automobile piston engine (the Tiny Friendly Giant) to an aircraft engine from an environmental and practical point of view. The problem of increased emissions from aviation calls for technical and socioeconomic solutions, which is the reason why this report is written. LÄS MER

  7. 25. Ventilering av brännbara gaser vid batteribränder

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Fredrik Gahm; [2021]
    Nyckelord :Lithium-ion batteries; thermal runaway; energy storage; battery storage; ventilation; explosion; explosion hazard.; Litiumjonbatterier; termisk rusning; energilager; batterilager; ventilation; explosion; explosionsrisk.;

    Sammanfattning : The use of lithium-ion batteries is something that is becoming more common in today’s society. They are found in a variety of electronic equipment such as mobile phones, laptops and tools. Several incidents have been reported due to lithium-ion batteries ending up in a state called thermal runaway. LÄS MER
