Selective 1-hexene/1-octene production with 1-decene

A process comprising:

• a) separating a composition comprising an oligomer product, the oligomer product comprising at least 85 mol % C6 olefins and at least 5 mol % C8+ olefins, into
• i) a first oligomer composition comprising C6 alkanes and at least 90 mol % C6 olefins, the C6 olefins comprising at least 90 mol % 1-hexene, and
• ii) a heavies stream comprising C8+ olefins;
• b) contacting a metathesis catalyst system with all or a portion of the first oligomer composition to form a first composition comprising C10 linear internal olefins;
• c) contacting all or a portion of the C10 linear internal olefins with a catalytic isomerization catalyst system in the presence of photochemical irradiation to form a second composition comprising 1-decene;
• and
• d) purifying the second composition to isolate a third composition comprising at least 90 mol % 1-decene.
