Treatment, of petroleum, residua, heavy oil, or bitumen with a low-boiling liquid hydrocarbon results in the separation of brown to black powdery materials known as asphaltenes (Figure 1-12). The reagents for effecting this separation are n-pentane and n-heptane, although other low molecular weight liquid hydrocarbons have been used (van Nes and van Westen, 1951; Mitchell and Speight, 1973).
