  1. 1. Cooling Potential of Methane in Rocket Nozzle Cooling Channels : A Conjugate Heat Transfer Analysis

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marcus Pettersson; [2019]
    Nyckelord :;

    Sammanfattning : The use of hydrocarbons as fuel in rocket propulsion has been of great interest to the aerospace industry in recent years. Specifically, natural gas with a high content of methane has taken the interest of several actors, among them Sweden-based GKN Aerospace who in collaboration with KTH Royal Institute of Technology have started the MERiT project.

    Sammanfattning : The combustion of fossil fuels has for a long time been a problem from an environmental and sustainability point of view, especially when it comes to the emissions of atmospheric carbon dioxide. The environmental concern has for instance shifted the attention towards finding new sustainable alternatives for producing chemicals and fuels, as a substitute to today’s dependence on fossil based crude oil.

  3. 3. Application of sorption-enhanced catalysis to ethanol reforming

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Jacky Ho; [2016]
    Nyckelord :Catalysis; adsorption; Li4SiO4; CaO; Ethanol reforming;

    Sammanfattning : Lithium orthosilicate (Li4SiO4) is known to be a high temperature CO2 capture material.This work was focused on comparing Li4SiO4 to the extensively studied CaO as an adsorbentin sorption enhanced catalysis. Thermogravimetric analysis was used to study the effects ofsorption temperature and compaction on Li4SiO4 using 15vol% CO2 in N2. LÄS MER
