Influence of Oxygen-Containing Functional Groups on Asphaltene Self-Diffusion Coefficient in Asphaltene-Xylene Systems
文献摘要：
Molecular simulations were carried out to investigate the self-diffusion coefficient of asphaltene in asphaltene-xylene systems, used as heavy oil models. The self-diffusion behavior of asphaltene in the asphaltene-xylene equilibrium system was mainly affected by the interaction between asphaltene molecules, with stronger interactions corresponding to a slower diffusion of asphaltene. The interactions between asphaltene molecules mainly included π-π interactions between aromatic rings and hydrogen bonds between strongly electronegative heteroatoms. These results are expected to provide theoretical guidance for reducing the viscosity of heavy oil.
