Dried asphaltenes<br />
http://baervan.nmt.edu/Petrophysics/group/intro-2-asphaltenes.pdf<br />
Figure 1. Examples of the appearance (magnified about 15 times) of asphaltenes separated from<br />
Mars-P crude oil with an excess of (a) n pentane (n-C5) <strong>and</strong> (b) n-heptane (n-C7).<br />
Some would argue that the n-C7 asphaltenes are the “real” asphaltenes, whereas the n-C5 material is a<br />
mixture of asphaltenes <strong>and</strong> resins.<br />
The “high end materials” in molecular weight, polarity <strong>and</strong> aromaticity — may separate into an<br />
asphaltene-rich phase in response to changes in pressure, composition, <strong>and</strong>/or temperature.<br />
