Catalytic Dehydrogenation of Propane: Oxidative and Non-Oxidative Dehydrogenation of Propane
(Master thesis, 2012)The dehydrogenation of propane has a great interest, due to a global growing demand in propene. This reaction needs a catalyst, high temperature and low propane partial pressure. During this work, platinum hydrotalcite-supported ... -
Catalytic Hydrodeoxygenation of Bio-oils with Supported MoP-Catalysts
(Master thesis, 2013)The goal of this thesis was to test the MoP catalysts which were made during autumn 2012, in a HDO reaction of phenol to benzene at a HDO rig. The catalysts were supported by Al2O3, SiO2, TiO2 and ZrO2, and they were ... -
Catalytic isomerization of light alkanes
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:160, Doctoral thesis, 2004)In recent years the levels of sulfur and benzene in the gasoline pool have been reduced, and in the future there may also be new regulations on vapor pressure and the level of aromatics and olefins as well. The limitations ... -
Catalytic Methane Abatement for Natural Gas Engines
(Master thesis, 2018)To reduce the greenhouse emissions it is proposed to use natural gas vehicles in the marine sector, instead of conventional vehicles using heavy fuel oil. Use of natural gas will reduce NOx, SOx and CO2 emissions, and will ... -
