Hydrogenation of N-propylcarbazole over supported ruthenium as a new prototype of liquid organic hydrogen carriers (LOHC)?
RSC Advances Pub Date: 2013-10-14 DOI: 10.1039/C3RA44760J
Abstract
We report full hydrogenation of N-propylcarbazole in molten state over a supported ruthenium catalyst at 120–150 °C. A remarkably fast reaction rate was achieved with the apparent activation energy of 18.4 kJ mol?1. Two stereoisomers of the final product were identified and the less stable one was found to dominate the product distribution at lower temperatures and/or with shorter reaction times, which is highly beneficial for hydrogen release upon dehydrogenation with better purity and for enhancement of catalyst performance. The optimum conditions for catalytic hydrogenation of N-propylcarbazole were found to be at 120 °C for 60 minutes.
