Description Liquid organic hydride (LOH) based H2 supply systems possess an excellent potential to
overcome the obstacles of upcoming ‘hydrogen economy’. However, their efficiency mainly
relies on the choice of organic hydride and the dehydrogenation catalyst. In the present
study, we focused on the former to strengthen the understanding of H2 supply through
LOH dehydrogenation. We investigated the role of various functionalities viz., methyl
group, N heteroatom, cyclic ring and their combinations in LOH dehydrogenation. Several
simple representative LOH's such as methylcyclohexane, piperidine, 4-methylpiperidine
and decalin were considered and their dehydrogenation was studied over a 5 wt% Pt/
ACC catalyst in a spray pulse reactor at 350 �C. The H2 evolution rates were found to follow
the trend: cyclohexane < methylcyclohexane < piperidine < 4-methylpiperidine < decalin.
The inductive effects caused by these functional groups and their impact on H2 evolution
were comprehensively described. Finally, the results were compared with the benchmark
reaction, cyclohexane dehydrogenation to benzene.
