Abstract

A method of reducing the acidity and fouling tendencies of distillates, when waste lubricating oil is distilled, which comprises treating the oil in a state when the oil has some water content, with one or more alkali metal salts of an acid that is weaker than sulphonic, or with a hydroxide of an alkali metal salt.
