1. Conceptualisation, Implementation and Commissioning of a Controlled Pyrolysis Rig : KTH Master Thesis Report
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Liquid methane has seen popular interest from industry and academia as a next-generation rocket fuel due to its favorable performance characteristics and potential for extra-terrestrial in-situ resource utilisation. Since the rocket combustion chamber and nozzle are subject to high heat loads, regenerative cooling is a standard method to achieve lower temperatures. LÄS MER
2. Experimental study on the effect of rocket nozzle wall materials on the stability of methane
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.

3. Characterization of NiMo catalysts with noble metal promoters
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : To be able to face the challenges brought on by climate change there is an urgent need to reduce the heavy dependence on fossil fuels. Bio-oil is one such renewable and carbon-neutral replacement that has shown promising potential. A key step in making bio-oil commercially feasible is improvements of the upgrading processes of the bio-oil. LÄS MER
4. Prospective Life Cycle Assessment of an Electrochemical Hydrogenation Process Over a Nickel Foam Cathode
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The need for a safe and sustainable chemical industry has called for the development of emerging technologies with improved environmental performance. In this study, an emerging electrochemical hydrogenation process over Ni foam is being developed at the laboratory scale with an expectation of less environmental impacts than a conventional palladium on carbon hydrogenation process.

5. Reforming of a Tar Model Compound Using Iron Catalysts
Master-uppsats, KTH/ProcessteknologiSammanfattning : Den internationella medvetenheten om hotet med växthusgaser har bidragit till en prioriterad utveckling av alternativa och rena tekniker baserade på förnybara i stället för fossila bränslen. Biomassaförgasning är en teknik för framställning av icke-fossil energigas från biomassa. LÄS MER
