Abstract:
1. A process for upgrading hydrocarbons comprising: a) separating a first hydrocarbon stream and a remaining hydrocarbon stream from a hydrocarbon feedstock in a first separation zone, wherein said first hydrocarbon stream comprises compounds having five carbon atoms per molecule (C5); b) reacting said first hydrocarbon stream in a metathesis reaction zone to form a metathesis reaction product stream, wherein said metathesis reaction product stream comprises compounds having less than five carbon atoms per molecule (C4−), compounds having five carbon atoms per molecule (C5), and compounds having at least six carbon atoms per molecule (C c) separating a second hydrocarbon stream and a third hydrocarbon stream from said metathesis reaction product stream in a second separation zone, wherein said second hydrocarbon stream comprises compounds having less than six carbon atoms per molecule (C5−) and wherein said third hydrocarbon stream comprises compounds having at least six carbon atoms per molecule (C6+); d) separating a fourth hydrocarbon stream and a fifth hydrocarbon stream from said second hydrocarbon stream in a third separation zone, wherein said fourth hydrocarbon stream comprising compounds having less than 5 carbon atoms per molecule (C4−) and said fifth hydrocarbon stream comprising compounds having 5 atoms per molecule (C5); and e) reacting said fourth hydrocarbon stream in a hydrocarbon upgrading zone wherein said process does not comprise dehydrogenation reactions.
