    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.

    摘要: A method for producing lubricant base oils is provided comprising the steps of: (a) separating a feedstock into a light lubricant base oil fraction and a heavy fraction; (b) hydroisomerizing the fractions over a medium pore size molecular sieve catalyst under hydroisomerization conditions to produce an isomerized light lubricant base oil fraction having a pour point less than or equal to a target pour point of the lubricant base oils and an isomerized heavy fraction having a pour point of equal to or greater than the target pour point of the lubricant base oils and a cloud point greater than the target cloud point of the lubricant base oils; and (c) dehazing the isomerized heavy fraction to provide a heavy lubricant base oil having a pour point less than or equal to the target pour point of the lubricant base oils and a cloud point less than or equal to the target cloud point of the lubricant base oils.
