This patent describes a method for stabilizing an oil fraction comprising hydrocarbons having an initial boiling point of about 200{degrees}F. to about 1050{degrees}F. It comprises: hydrotreating an oil feedstock comprising an aromatic-containing oil fraction to be stabilized containing at least about 1 weight percent of nitrogen, said oil fraction to be stabilized comprising hydrocarbons having an initial boiling point of about 200{degrees}F. to about 1050{degrees}F. and a hydrogen-to-carbon atomic ratio of at least about 1.4 in a hydrotreated to reduce the nitrogen content of said fraction to be stabilized to a range of about 200 ppm to abut 10,000 ppm and to also reduce the aromatic content of said oil fraction to result in a hydrotreated material liquid yield of greater than 100 percent; and removing condensed aromatic compounds from at least said oil fraction to be stabilized of said hydrotreated feedstock to yield a stable oil fraction.
