- Abstract
- This study presents the results of an investigation into the properties of bulk nickel-based catalysts Cu/Ni-SiO, Zn/Ni-SiO, and Sn/Ni-SiO for the reversible toluene hydrogenation/methylcyclohexane dehydrogenation processes used in hydrogen storage technology. A comprehensive physicochemical characterization was carried out, including low-temperature nitrogen adsorption, X-ray diffraction, CO chemisorption, H temperature-programmed reduction, and temperature-programmed desorption of toluene. It was established that the modification of nickel catalysts with Cu, Zn, and Sn significantly affects the structure of active phases and catalyst properties. The highest selectivity toward toluene in the dehydrogenation of methylcyclohexane was exhibited by zinc- and tin-modified catalysts, with selectivity values of 97 and 99%, respectively. The obtained results confirm the feasibility of developing efficient dehydrogenation catalysts for liquid organic hydrogen carriers (LOHCs) based on nickel without the use of noble metals.
