  • Publication number: 20250154292
    Abstract: Provided is a method for producing a C9 hydrogenated resin by reusing a thermally polymerized liquid resin. The method includes: preheating a polymerization reaction material by a feed heat exchanger using a polymerization liquid as a heat source, and then subjecting a resulting preheated polymerization reaction material to polymerization in a polymerization reactor group; transferring a mixed liquid of unpolymerized C9 and a liquid resin evaporated from a flash evaporation system (11) to a refining tower (9), and performing refining; subjecting a thermally polymerized resin obtained from a bottom of the flash evaporation system (11) to hydrogenation to synthesize a hydrogenated resin; and using a refined liquid resin obtained from the refining tower (9) as a vacuum mother liquor of the vacuum pump (18), and then returning the refined liquid resin to the polymerization reactor group, and making the refined liquid resin to participate in the polymerization.
