"Complex viscosities of Athabasca bitumen (Alberta, Canada) and Maya crude oil (Mexico) samples, along with their permeates and retentates obtained by nanofiltration at 473 K through 5-, 10-, 20-, 50-, and 200-nm ceramic membranes, were investigated over the temperature interval of 298-373 K. The pentane-asphaltene 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
"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 ...
