(57) [Problem] A metathesis catalyst that is easy to separate and purify, easily reuses, has high activity, suppresses side reactions such as olefin isomerization and olefin polymerization, exhibits high selectivity, and has a long life. To provide. SOLUTION: The present invention provides an olefin metathesis reaction catalyst using mesoporous alumina as a carrier, and particularly an olefin metathesis reaction catalyst using mesoporous alumina as a carrier having a maximum peak in a pore distribution in a range of 1 to 10 nm. |
