Abstract
A process for producing distillate fuels, such as diesel fuels and jet fuels having both high lubricity and low sulfur levels. Such fuels are produced by fractionating a distillate feedstream into a light fraction which is relatively low in lubricity and which contains from about 50 to 100 wppm of sulfur and a heavy fraction having a relatively high lubricity. The first fraction is hydrotreated to remove substantially all of the sulfur and is then blended with the second fraction to produce a distillate fuel product having relatively low sulfur levels and a relatively high lubricity.
