Information about the composition of petroleum residues is needed because of the increased use of this material as an energy source. This study is an extension of previous work in which high-boiling distillates from four crude oils were characterized according to compound type. The residues used in this investigation represent the portions of the crude oils that did not distill at a corrected boiling point of 675/sup 0/C. The residues were separated into fractions of acids, bases; neutral nitrogen compounds, and hydrocarbons, using the separation technique developed for high-boiling distillates. Acids and bases were isolated using ion exchange resins, neutral nitrogen compounds were removed by complexation chromatography, and the hydrocarbons were separated into fractions of saturates and aromatics by adsorption chromatography. The acid and base fractions were further separated and characterized according to compound type using such methods as gel permeation and adsorption chromatography and infrared, ultraviolet, and high-resolution mass spectrometry.
