Title:
APPARATUS AND METHOD FOR REMOVING HALOGENS GENERATED DURING PREPARATION OF POLYBUTENE
Document Type and Number:
WIPO Patent Application WO/2015/030489
Kind Code:
A1
Abstract:
Disclosed are an apparatus and a method for removing halogens generated during the preparation of polybutene, which are capable of improving the utilization of polybutene and light polymers by removing halogen components contained in the polybutene and the light polymers. The method for removing halogens generated during the preparation of polybutene comprises the steps of: generating a reactant by supplying and polymerizing a catalyst and a reaction material; removing and neutralizing a catalyst component from the reactant; separating the reactant into an organic compound and impurities containing a catalyst component; distilling unreacted materials by heating the organic compound; and removing, by using a halogen-removing catalyst, halogen components of a polymer mixture remaining after the distillation, or removing, by using a halogen-removing catalyst, halogen components of polybutene and light polymers obtained from the polymer mixture.
