Abstract
A process to produce 1-octene and 1-decene includes (a) separating a composition containing an oligomer product—which contains 15 to 80 mol % Colefins, 20 to 80 mol % Colefins, and 5 to 20 mol % C+ olefins—into a first oligomer composition containing Calkanes and at least 85 mol % Colefins (e.g., 1-hexene), a second oligomer composition containing at least 20 mol % Colefins (e.g., 1-octene), and a heavies stream containing C+ olefins, then (b) contacting a metathesis catalyst system with the first oligomer composition to form a first composition comprising Clinear internal olefins, (c) contacting the Clinear 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. Processes to produce 1-hexene and 1-decene also are described, as well as related manufacturing systems and processes to produce higher carbon number normal alpha olefins from lower carbon number normal alpha olefins.
