Abstract
A method for producing linear monoolefins comprises a step of contacting a raw material composition containing a first linear monoolefin having 4 to 8 carbon atoms with an isomerization catalyst at 250 to 390° C. in the presence of 20 ppm by volume or more of molecular oxygen and/or 20 ppm by volume or more of water to perform an isomerization reaction for isomerizing at least a part of the first linear monoolefin to a second linear monoolefin having a different double bond position, wherein the catalyst contains zeolite.
