Title: Upgrading heavy gas oils

Abstract

A method is described of neutralizing the organic acidity in heavy gas oils to produce a neutralization number less than 1.0 whereby they are rendered suitable as lube oil feed stocks which consists essentially of treating the heavy gas oils with a neutralizing amount of monoethanolamine to form an amine salt with the organic acids and then heating the thus-neutralized heavy gas oil at a temperature at least about 25/sup 0/F greater than the boiling point of water and for a time sufficient to convert the amine salts to amides.
