Popis

Application

• Study on the selective hydrogenation of isophorone: This research explores the hydrogenation process of isophorone, achieving low conversion with high TMCH (3,3,5-Trimethylcyclohexanone) selectivity. The focus is on optimizing conversion rates (L Xu, S Sun, X Zhang, H Gao, W Wang - RSC advances, 2021).
• Synthesis of aviation fuel from bio-derived isophorone: Investigates the use of isophorone as a precursor for synthesizing energy-dense polycyclic cyclobutane, applicable in aviation fuel production (CF Ryan, CM Moore, JH Leal - Sustainable Energy & Fuels, 2020).
