    摘要： A process for manufacturing a lubricating base oil, comprising dewaxing a substantially paraffinic wax feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve under hydroisomerization conditions including a hydrogen to feed ratio from about 712.4 to about 3562 liter H2/liter oil, whereby a lubricating base oil is produced having a) a total weight percent of molecules with cycloparaffinic functionality greater than 10, and b) a ratio of weight percent molecules with monocycloparaffinic functionality to weight percent molecules with multicycloparaffinic functionality greater than 30. Also a method for producing a base oil having a high ratio of weight percent molecules with monocycloparaffinic functionality to weight percent molecules with multicycloparaffinic functionality by hydroisomerization dewaxing a selected Fischer-Tropsch wax under hydroisomerization conditions including a hydrogen to feed ratio from about 712.4 to about 3562 liter H2/liter oil. Also a lubricating base oil manufacturing plant.

    摘要： A process to manufacture a base oil, comprising selecting an original base oil having an original VI, an original volatility, and an original CCS VIS; and removing a lower boiling fraction, whereby the base oil is made having a kinematic viscosity at 100° C. from 4.2 to 4.6 mm2/s, a VI that is at least 4 higher than the original VI, a volatility that is at least 3 wt % lower than the original volatility, and a CCS VIS that is within 200 mPa·s of the original CCS VIS. A process to manufacture a base oil, comprising selecting an original base oil and removing a lower boiling fraction from the original base oil, whereby the base oil has a ratio of a Noack Volatility to a CCS VIS at −25° C. multiplied by 100 from 0.80 to 1.55. Also a base oil, made by the processes disclosed herein.
