Method for producing a plurality of lubricant base oils from paraffinic feedstock

摘要

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