1. 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
2. Nanoscale characterisation of model Ni-Mo catalyst active phases
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Centrum för analys och syntesSammanfattning : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. LÄS MER
3. Generation of Model NiMo Hydrotreating Nano-catalyst via the Spark Discharge Technique
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Establishing a technically practical method to generate representative model catalysts for the use in characterizations and testing prior to catalyst implementation in chemical process units would allow for a more sophisticated understanding of the underlying catalytic mechanisms. As a step towards establishing such a method, generating non-agglomerated, spherical NiMo nanoparticles, with diameters below 25 nm and atomic composition of maximum 30 at% Ni with Mo (maximum 3:7 Ni:Mo atomic ratio), for application as model hydrotreating catalysts, was addressed.
