    Abstract: Processes for the production of high purity alpha olefins from a mixture of olefins are disclosed. The processes may include: contacting propylene and a hydrocarbon mixture comprising a mixture of olefins having a carbon number n with a first metathesis catalyst to form a metathesis product comprising a beta-olefin having a carbon number n+1, an alpha-olefin having a carbon number n−1, as well as any unreacted propylene and olefins having a carbon number n. The metathesis product may be fractionated to recover a fraction comprising the beta-olefin having a carbon number n+1. Ethylene and the fraction comprising the beta-olefin having a carbon number n+1 may then be contacted with a second metathesis catalyst to form a second metathesis product comprising an alpha-olefin having a carbon number n and propylene, which may be fractionated to form a propylene fraction and a fraction comprising the alpha olefin having a carbon number n.

    Abstract: Processes for the production of olefins are disclosed, which may include: contacting a hydrocarbon mixture comprising linear butenes with an isomerization catalyst to form an isomerization product comprising 2-butenes and 1-butenes; contacting the isomerization product with a first metathesis catalyst to form a first metathesis product comprising 2-pentene and propylene, as well as any unreacted C4 olefins, and byproducts ethylene and 3-hexene; and fractionating the first metathesis product to form a C3-fraction and a C5 fraction comprising 2-pentene. The 2-pentene may then be advantageously used to produce high purity 1-butene, 3-hexene, 1-hexene, propylene, or other desired products.
