The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. In crude oil a high pour point is generally associated with a high paraffin content, typically found in crude deriving from a larger proportion of plant material. That type of crude oil is mainly derived from a kerogen Type III.

InactiveUS6080301ARefining to change hydrocarbon structural skeletonHydrocarbon purification/separationParaffin waxAlkane
A premium synthetic lubricating oil base stock having a high VI and low pour point is made by hydroisomerizing a Fischer-Tropsch synthesized waxy, paraffinic feed wax and then dewaxing the hydroisomerate to form a 650-750 DEG F.+ dewaxate. The waxy feed has an initial boiling point in the range of about 650-750 DEG F., from which it continuously boils up to at least 1050 DEG F. and has a T90-T10 temperature difference of at least 350 DEG F. The feed is preferably hydroisomerized without any pretreatment, other than optional fractionation. The 650-750 DEG F.+ dewaxate is fractionated into two or more base stocks of different viscosity.
