ABSTRACT:
Olefins and alcohols present in Fischer-Tropsch products are converted to primary and secondary alkyl alcohols having at least four carbons through acid catalyzed etherification and hydrolysis reactions. The alcohols are added to a highly isoparaffinic distillate fuel blend, improving the lubricity of the mixture, and forming a distillate fuel with improved lubricity.
