Investigating Change of Polydispersity and Rheology of Crude Oil and Bitumen by johnson is a document available to read on EtoBox.
This study investigates the effects of asphaltene oxidation on the polydispersity and rheology of bitumen, hypothesizing that oxidation increases polydispersity, which in turn reduces viscosity and crossover modulus. Laboratory experiments and molecular dynamics simulations were conducted, revealing that increased concentrations of oxidized asphaltenes lead to decreased viscosity at high shear rates due to the formation of nanoaggregates. The findings emphasize the importance of controlling asphaltene oxida
