Abstract
Disclosed are an apparatus and method for preparing polybutene having various molecular weights by using complex catalysts of different molar ratios. The apparatus for preparing polybutene having various molecular weights, comprises: a complex catalyst preparing device for preparing a high-activity complex catalyst and a low-activity complex catalyst to form highly reactive polybutene through polymerization; a high-molar ratio complex catalyst system for controlling the storage and supply of the high-activity complex catalyst; a low-molar ratio complex catalyst system for controlling the storage and supply of the low-activity complex catalyst; and a reactor to which reaction raw materials including the high-activity complex catalyst, the low-activity complex catalyst, and isobutene are supplied to be polymerized into highly reactive polybutene.
