The characterization of asphaltenes recovered from different crude oils is reported in the present work. The properties of the crude oils cover a wide range (API gravity: 10–33°, asphaltene content: 1.7–25.1wt.%). Asphaltenes were precipitated in a high pressure batch reactor using n-heptane as solvent. Metal content by atomic absorption, elemental analysis, UV-fluorescence spectroscopy and molecular...
