Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a chromium-containing catalyst system for trimerization, oligomerization and/or polymerization of an olefin, having improved activities and selectivity. SOLUTION: Chromium (III) 2-ethylhexanoate of 0.14 g is weighed and inserted into 25 mL pressure tube, and pyrrol of 0.062 g and cyclohexane as a diluent are added thereto to provide a solution. The obtained solution of 0.9 mL, and 1.1 Mol solution of triethylaluminum in heptane of 0.9 mL are added to an 1 L autoclave having cyclohexane of 300 mL in a countercurrent ethylene to provide the objective catalyst. The autoclave is sealed and the feed of the ethylene is stopped, and the temperature of the autoclave is raised to 80 deg.C of the reaction temperature. After reaching the reaction temperature, the pressure of the ethylene is increased to 550 psig and ethylene is successively fed for 30 min to provide the objective hexenes in 89% yield.
