Abstract
Provided is a method for preparing a polyethylene polymerization catalyst including a first mixed solution preparation step of mixing a magnesium compound, a first hydrocarbon compound, and alcohol to prepare a first mixed solution; a viscosity adjustment step of adding a second hydrocarbon compound to the first mixed solution to adjust a viscosity of the first mixed solution; a second mixed solution preparation step of adding a first internal electron donor to the first mixed solution having an adjusted viscosity to prepare a second mixed solution; and a recrystallization step of adding a transition metal compound to the second mixed solution to perform recrystallization.
