The pentaneasphaltene content of the samples varied from 1.5 wt% to 57.2 wt %, whereas the asphaltene-free composition of the samples did not vary from the feed composition (within experimental error). At temperatures of <323 K, part of the maltenes of both of these hydrocarbon resources is solid. The solid maltene fraction is a function of temperature. If this additional solid is taken into account, the experimental relative viscosities for both Athabasca bitumen- and Maya crude-related samples fall on a single master curve, over the entire temperature interval, irrespective of the asphaltene content.
