OLEO DE BASE LUBRIFICANTE SINTETICO SUPERCARBURANTE |
摘要 |
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°F+ dewaxate. The waxy feed has an initial boiling point in the range of about 650-750°F, from which it continuously boils up to at least 1050°F and has a T 90 -T 10 temperature difference of at least 350°F. The feed is preferably hydroisomerized without any pretreatment, other than optional fractionation. The 650-750°F+ dewaxate is fractionated into two or more base stocks of different viscosity.
