ABSTRACT:
A process of producing olefins by a metathesis reaction in a practical low temperature range by improving the reactivity of the catalyst is provided.The process of producing olefins according to the present invention allows a metathesis reaction of olefins, which uses a catalyst containing metal elements such as tungsten, molybdenum, rhenium or the like, to proceed at an industrially sufficient reaction rate in a practical low temperature range, by using a compound containing at least one metal element selected from the metals of Group Ia (alkali metals), Group IIa (alkaline earth metals), Group IIb and Group IIIa as co-catalyst and allowing hydrogen gas to co-exist with the reaction raw material.
