It was found that the NiO-ZrO2 catalyst containing 25 mole percent of nickel oxide and evacuated at 400‡C for 1.5 hr showed maximum catalylic activities for 1-butene isomerization and ethylene dimerizalion. The catalytic activities for both isonierization and dimerizalion were correlated with the acid strengths of the catalysts. The isonierization activity of 1-butene ran parallel with the dimerization activity of ethylene, although the isomerization look place on relatively weak acid sites as compared with the dimerization.
