Studies on the interfacial dilational rheology of films containing heavy oil fractions as related to emulsifying properties

摘要: Abstract In this research, the heavy oil emulsifying and viscosity reducing properties of a series polyethers have been studied by emulsion stability analysis measurements. The experimental results show that (with molecular weights 8400, 12,600 14,600) are efficient surfactants for emulsification reduction. To illustrate mechanisms, we carried out study interfacial tension dilational rheology resins asphaltenes in strong activity. adsorption active components will form film with certain intensity, which may help to stable W/O emulsion. On other hand, reduce sub-layer construction at higher concentration, leads formation elastic layer strength. For mixed systems polyethers, layers almost same just as used alone, demonstrating be occupied mainly polyether molecules. water-soluble suitable structure film, helpful forming O/W obviously.
