Pour point depressant for hydrocarbon compositions |
| abstract |
Disclosed in one embodiment is a hydrocarbon blend made from 0.001 to 10 wt % of at least one poly-α-olefin, by weight of the blend, the at least one poly-α-olefin having a Kv 100 within the range of from 10 to 3000 cSt and a molecular weight distribution within the range of from 1.0 to 4.5; and a base stock having a Kv 100 below 20.0 cSt; wherein the at least one poly-α-olefin is present in an amount sufficient to lower the pour point of the blend by at least 5° C. relative to the pour point of the base stock. In certain embodiments the blend is formed by (a) reacting a catalyst composition and a feed containing at least two sets of α-olefins, wherein the first set of α-olefins is selected from C 4 to C 12 α-olefins and the second set of α-olefins is selected from C 14 or larger α-olefins. The α-olefin feed may have a number average carbon number of at least 8 carbon atoms or greater. |
