Abstract

See full text

Methods are provided for upgrading asphaltene-depleted crude fractions. The asphaltene-depleted crude fractions are upgraded by oxidizing the crude fractions by air blowing. Upgrading an asphaltene-depleted crude fraction can allow more valuable grades of asphalt to be formed from the crude fraction. Alternatively, upgrading an asphaltene-depleted crude fraction can allow for incorporation of a greater percentage of such a crude fraction in a blend of crudes that are used for making a desired grade of asphalt.
