Use of Biosourced Molecules as Liquid Organic Hydrogen Carriers (LOHC) and for Circular Storage

Reactions
The use of Liquid Organic Hydrogen Carriers (LOHC) is one of the potential options to store hydrogen. Today, the vast majority of compounds used as LOHC come from the oil industry. Using biosourced LOHC would be a step forward in the development of this CO2-free solution. This article looks at LOHC candidates that can be obtained from biomass.

Hydrogenation of N-propylcarbazole over supported ruthenium as a new prototype of liquid organic hydrogen carriers (LOHC)

RSC Advances, 2013
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 ...
