Abstract

See full text

A process to produce 1-octene and 1-decene includes (a) separating a composition containing an oligomer product—which contains from 15 to 80 mol % C6 olefins, from 20 to 80 mol % C8 olefins, and from 5 to 20 mol % C10+ olefins—into a first oligomer composition containing C6 alkanes and at least 85 mol % C6 olefins (e.g., 1-hexene), a second oligomer composition containing at least 85 mol % C8 olefins (e.g., 1-octene), and a heavies stream containing C10+ olefins, then (b) contacting a metathesis catalyst system with the first oligomer composition to form a first composition comprising C10 linear internal olefins, (c) contacting the C10 linear internal olefins with an isomerization hydrofunctionalization catalyst system to form a second composition containing a functionalized alkane, (d) retro-hydrofunctionalizing the functionalized alkane to form a third composition containing 1-decene, and (e) purifying the third composition to isolate a fourth composition containing at least 90 mol % 1-decene. Processes to produce 1-hexene and 1-decene also are described, as well as related manufacturing systems.
