ISOMERIZATION/DEHAZING PROCESS FOR BASE OIL FROM FISCHER-TROPSCH WAX

Title:

ISOMERIZATION/DEHAZING PROCESS FOR BASE OIL FROM FISCHER-TROPSCH WAX

Document Type and Number:

Japanese Patent JP2011236439

Kind Code:

A

Abstract:

To provide a low-cost, low-complexity process for producing a plurality of lubricant base oils with acceptable pour points, viscosity indices, and yields from a broad boiling range feedstock.

The 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 equal to or less than 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 equal to or less than the target pour point of the lubricant base oils and a cloud point equal to or less than the target cloud point of the lubricant base oils.
