POUR POINT DEPRESSANT FOR HYDROCARBON COMPOSITIONS

摘要

Disclosed is a hydrocarbon blend made from 0.001 to 10 wt% of at least one poly-a- olefin, by weight of the blend, the at least one poly-a-olefm having a Kv100 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 Kv100 below 20.0 cSt; wherein the at least one poly-a-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. The blend is formed by (a) reacting a catalyst composition and a feed containing at least two sets of a-olefins, wherein the first set of a-olefins is selected from C4 to C12 a-olefins and the second set of a-olefins is selected from C14 or larger a-olefins. The a-olefin feed may have a number average carbon number of at least 8 carbon atoms or greater.
