(57) Abstract : A process is provided for treating a basic metal oxide olefin isomerization catalyst, such as magnesium
oxide. The catalyst is activated by contact with a deoxygenated nitrogen containing not more than 5 ppm molecular
oxygen by volume under activation conditions. The olefin isomerization process and catalyst described herein are
advantageously used for the production of a terminal olefin such as 1-butene from an internal olefin such as 2-butene.
