Boron And Rare Earth Oxide Composite Nanoparticles For Enhancement Of Combustion, Jacob Hanberry
Boron And Rare Earth Oxide Composite Nanoparticles For Enhancement Of Combustion, Jacob Hanberry
LSU Master's Theses
Metallic fuels are of interest as additives in bio-fuel combustion because of their high heating values, and this thesis deals with the experimental investigation of boron nanoparticles and their effect on ethanol combustion. Two grades of boron nanoparticles were commercially purchased and modified to obtain different physical characteristics, by ball milling and sintering. Also, a mixture of rare-earth oxide (CeO2, La2O3, and Gd2O3) nanoparticles was synthesized and added to the boron nanoparticles in varying amounts to form composite mixtures. The effects of rare-earth oxides on boron combustion were investigated using these composites. Particle characterizations were carried out by X-ray diffraction, …

Catalytic Hydrogenation Of Co To Higher Alcohols, Nachal Devi Subramanian
LSU Doctoral Dissertations
The interest in converting synthesis gas to alcohols and oxygenated fuel additives via CO hydrogenation is growing rapidly due to the increasing rise in oil prices. Among the potential end products, ethanol is desirable since it serves as a clean alternative fuel, a gasoline blend, and a hydrogen carrier to supply fuel cells. The high cost and limited availability of the most active/selective Rh-based catalysts has led to the development of base metal catalysts such as modified Cu-based catalysts. Literature suggests that a combination of Co (or Mn) with Cu can facilitate higher alcohol formation by a non-dissociative adsorption of …
