    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 hydraulic fluid composition having excellent seal compatibility is prepared from an isomerized base oil is provided. The composition comprising (i) 80 to 99.999 wt. % of a lubricating base oil having consecutive numbers of carbon atoms, less than 10 wt % naphthenic carbon by n-d-M, less than 0.10 wt. % olefins and less than 0.05 wt. % aromatics, a molecular weight of greater than 600 by ASTM D 2503-92 (Reapproved 2002), a wt % total molecules with cycloparaffinic functionality greater than 25 and a ratio of molecules with monocycloparaffinic functionality to molecules with multicycloparaffinic functionality greater than 10; and (ii) optionally from 0.001 to 6 wt % of a viscosity modifier; and (iii) 0-10 wt % of at least an additive package. When used in operations, the composition results in an average volume change in a rubber seal of less than 3% and an average hardness change in the rubber seal of less than 1 pts. when tested under ASTM D 471-06 (SRE NBR1 at 100° C., 168 hours).
