1. 1. Generation of Model NiMo Hydrotreating Nano-catalyst via the Spark Discharge Technique

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Nyckelord :Model catalyst systems; hydrotreating catalysts; NiMo catalysts; Spark discharge technique; nanoparticles; chemical engineering; kemiteknik; Technology and Engineering;

   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.
