Abstract Understanding how hydrotreating oxygen-containing compounds together with nitrogen-containing affects the reactivity and selectivity is relevant for processing renewable feedstocks. In this work, competitive hydrodeoxygenation (HDO) hydrodenitrogenation (HDN) reactions were studied by co-hydrotreating palmitic acid (C16 acid) tetradecylamine (C14 amine) over a Pt/ZrO 2 catalyst in batc...
