Method for producing highly reactive polybutene
A method for preparing polybutene by polymerization of a raw material of a carbon number 4 (C4) compounds having an isobutene amount of 50 to 75% by weight, is disclosed. The raw material of C4 compounds is selected from the group consisting of (a) C4 compound material obtained by adding high purity isobutene to C4 raffinate-1; (b) C4 compound material obtained by adding high amount isobutene mixture which is generated in an olefin conversion unit (OCU) process to C4 raffinate-1; (c) C4 compound material obtained by adding high purity to butane-butene oil (B-B oil); (d) C4 compound material obtained by adding high amount isobutene mixture which is generated in an olefin conversion unit (OCU) process to butane-butene oil (B-B oil); (e) C4 compound material obtained by adding a dilute solvent to high purity isobutene; (f) C4 compound material obtained by adding a dilute solvent to high amount isobutene mixture which is generated in an olefin conversion unit (OCU) process; (g) C4 compound material obtained by adding high purity isobutene to a mixture generated in dehydrogenation reaction that converts isobutane to isobutene; and (h) C4 compound material obtained by adding high amount isobutene mixture which is generated in an olefin conversion unit (OCU) process to a mixture generated in dehydrogenation reaction that converts isobutane to isobutene.
