Title:
METHOD FOR PRODUCING C9 HYDROGENATED RESIN BY RECYCLING THERMAL POLYMERIZATION LIQUID RESIN
Document Type and Number:
WIPO Patent Application WO/2024/027131
Kind Code:
A1
Abstract:
A method for producing C9 hydrogenated resin by recycling thermal polymerization liquid resin, belonging to the field of petroleum resin. A reaction process comprises: polymerization reaction materials are first preheated by a feed heat exchanger with a polymerization liquid as a heat source and then enter a polymerization reaction kettle group to undergo a polymerization reaction, and a non-polymerized C9 and liquid resin mixed solution obtained from a flash system (11) by means of flashing is transferred into a refining column (9) for refining; thermal polymerization resin taken out from the bottom of the flash system (11) enters the next-stage hydrogenation process to synthesize hydrogenated resin; and liquid resin taken out from the refining column (9) is first used as a vacuum mother liquor of a vacuum pump (18), and then returns to the polymerization reaction kettle group to participate in the polymerization reaction. The present invention has the advantages of the polymerization process producing no taken-out liquid resin, the amount of liquid resin of the hydrogenation process being small, avoiding hydrogen waste during subsequent hydrogenation processes, etc.; the liquid resin is recycled to participate in the polymerization reaction again to achieve chain growth, thereby improving the overall conversion rate of active components.
