Behaviors of asphaltene molecules in toluene under a shear force field were investigated by dissipative particle dynamics (DPD). The results showed that aggregated into nanoaggregates (NAs) three forms, mainly the face-to-face type, which contained up to 7 molecules. In aggregates, distance between aromatic sheets (ASes) adjacent was about 6 Å, and minimum 5.49 Å. composition NAs changed dynamically. absence shear, aggregates lasted for more than 3000 ps 8000 ps. an aggregate might reaggregate once dispersed. Both number size decreased field, duration less 1000 direction ASes distributed randomly when rate zero. Once sheared, angle plane while range it expanded. tended be parallel two concentrated below 40°. As increased, distribution concentrated.

In the heavy petroleum industry, development of efficient demulsifiers for effective breaking interfacially active asphaltenes (IAA)-stabilized water-in-heavy oil (W/HO) emulsions is a highly attractive but challenging goal. Herein, novel nitrogen and oxygen containing demulsifier (JXGZ) with strong hydrogen bonding has been successfully synthesized through combining esterification, polymerization amidation. Bottle tests indicated that JXGZ effectual in quickly demulsifying IAA-stabilized W/HO emulsions; complete dehydration (100%) to could be achieved 4 min at 55 °C using 400 ppm JXGZ. addition, effects concentration, temperature time on demulsification performance are systematically analyzed. Demulsification mechanisms reveal excellent attributed between water molecules (dual swords synergistic effect under bond reconstruction). The interaction "dual effect" generated by two types bonds can break non-covalent force (π-π stacking, Van der Waals force, bonds) IAA oil-water interface, promote aggregation coalescence finally achieve emulsions. These findings indicate shows engineering application prospects emulsions, this work provides key information developing more chemical suitable large-scale industrial applications.
