eng Abstract:
[eng][cze] It is known that acidity of supports plays a positive role in HDN. Thus, the Pt-Mo system was now deposited on a more acidic support than alumina, i.e. on an amorphous silica-alumina (ASA) in attempt to further enhance the HDN activity and HDN/HDS selectivity. The objective was to find how acidic support may affect the catalytic properties of the Pt-Mo system. The strongest effect was observed in HDN. Je známé, že kyselost nosičů hraje pozitivní roli v hydrodesulfurizaci (HDS). Proto jsme Mo-Pt systém nanesli na daleko více kyselý nosič jako alumina a to na amorfní silica-aluminu ve snaze zlepšit hydrodenitrogační (HDN) aktivitu a HDN/HDS selektivitu. Cílem bylo najít jak může kyselý nosič ovlivňovat katalytické vlastnosti Pt-Mo systému.
