1. A method for producing a hydrogenated petroleum resin, the method comprising:
polymerizing a cyclopentadiene-based compound and an aromatic vinyl compound, thereby obtaining a polymer; hydrogenating the polymer to prepare a molten hydrogenated petroleum resin; and granulating the molten hydrogenated petroleum resin, thereby obtaining hydrogenated petroleum resin pellets, wherein the granulating comprises sucking a low-molecular mist generated from the molten hydrogenated petroleum resin through a suction path having a filter in a granulator, and removing the low-molecular mist with the filter.
