16. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method
Master-uppsats, KTH/EnergiteknikSammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER
17. Point source carbon capture by porous inorganic carbonates
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

18. CFD calculations and comparison with measured data in a film cooled 1.5 stage high pressure test turbine : With two configurations of swirlers clocking
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : The gas turbine has an important role for the energy distribution due to its stability and flexibility. By increasing turbine inlet temperature (TIT) an increased thermal efficiency of the turbine can be achieved. The biggest limitation of the TIT is the material of the turbine components. LÄS MER
19. CFD simulation of dip-lubricated single-stage gearboxes through coupling of multiphase flow and multiple body dynamics : an initial investigation
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : Transmissions are an essential part of a vehicle powertrain. An optimally designed powertrain can result in energy savings, reduced environmental impact and increased comfort and reliability. Along with other components of the powertrain, efficiency is also a major concern in the design of transmissions. LÄS MER
20. Analysis and improvements of outdoor hot benches in Gävle
Magister-uppsats, Högskolan i Gävle/EnergisystemSammanfattning : Five exterior hot benches have been installed in Gävle, in Kyrkogatan street by the company Gävle Energi with the aim of achieving the wellnes of people that sit on them. This system uses the residual heat from the district heating, representing consequently a non-polluting system. LÄS MER
