In the transportation and storage system of hydrogen, being proprietary technology, by using methylcyclohexane/toluene carrier, development of dehydrogenation catalysts with high activity and stability are significant key technologies. In order to further improve resistance to coke formation, modified dehydrogenation catalyst, consisting of platinum supported on aluminum oxide, was newly developed by Chiyoda Corporation. It was demonstrated that this proprietary catalyst gave excellent performance in small reactor at commercial scale. In this presentation, excellent performance of the present modified catalyst will be presented.
