"Olefin Production Process"

Abstract: A process is provided which is capable of producing olefins stably and efficiently by a metathesis reaction of identical or different olefins while preventing the lowering in metathesis catalyst activity due to trace impurities such as heteroatom-containing compounds that are contained in a starting olefin. The olefin production process includes supplying a starting olefin containing more than 0 ppm by weight to not more than 10 ppm by weight of one or more kinds of heteroatom-containing compounds to a reactor that contains a metathesis catalyst and an isomerization catalyst, the metathesis catalyst including at least one metal element selected from the group consisting of tungsten, molybdenum and rhenium, the isomerization catalyst including calcined hydrotalcite or yttrium oxide, and performing a metathesis reaction of identical or different olefins.
