The present invention relates to a hydrogenation catalyst having a metal catalyst (core) / carbon (shell) structure and a process for producing the same, and more particularly, to a process for producing a hydrogenation catalyst which prevents leaching of an active metal in a liquid hydrogenation reaction of an organic acid such as levulinic acid, (Core) / carbon (shell) structure having a metal catalyst and a process for producing the same. The present invention further relates to a process for preparing a cyclized compound using the liquid hydrogenation catalyst. |
