| Abstract: | Residues from four crude oils have been separated into fractions of acids, bases, neutral nitrogen compounds, saturate hydrocarbons, and aromatic hydrocarbons. The separation scheme is a modification of a separation scheme originally developed for high-boiling petroleum distillates. The gross compositions of the four residues are compared. |
