Disclosed is a process for producing an olefin, in which the double bond isomerization of starting material olefins can be promoted to inhibit a metathesis reaction, which is a side reaction, thereby increasing the selectivity for the desired product. Also disclosed is a process for producing an olefin, in which the activity of a metathesis catalyst can be maintained for a long period and the deterioration in performance of a catalyst for promoting the double bond isomerization of the starting material olefins (i.e., an isomerization catalyst) can be prevented, thereby producing the desired product with high productivity and high efficiency.nSpecifically disclosed is a process for producing an olefin, which comprises reacting the same types or different types of raw material olefins with each other to produce an olefin having a different structure from those of the starting material olefins, which is characterized by using both a catalyst comprising at least one metal element selected from tungsten, molybdenum and rhenium and another specific catalyst. |
