Figure 5

m/z 133+134 mass chromatograms of the aromatic fractions separated from asphaltene pyrolysates at different temperatures. Filled circles indicate AIPs, and unfilled triangles indicate newly identified AAs. The mass chromatogram of the pyrolysates obtained at 260 °C, which is almost the same as those at 280 °C and 300 °C, was not shown here.
