    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 for producing an API Group I base oil, comprising: blending a lower quality base oil that does not meet API Group I specifications with a Fischer-Tropsch derived distillate fraction having defined pour point, viscosity index and Oxidator B, and isolating an API Group I base oil that has improved defined properties. A process for producing an API Group I base oil, consisting essentially of: (a) selecting a lower quality base oil not meeting API Group I specifications, having defined saturates, viscosity index and Oxidator BN; and (b) blending the lower quality base oil with a Group II base oil and a Fischer-Tropsch derived base oil. A process for improving the lubricating properties of a lower quality base oil. Also, a process for operating a base oil plant.
