Investigation of Asphaltene Adsorption at Liquid-Liquid and Liquid-Solid Interfaces
<p>Asphaltenes, as indigenous components in crude oils, are believed to play an important role in the petroleum production and processing industry. For example, asphaltene molecules can adsorb onto the water / oil interface like the amphiphiles and hinder water droplet coalescence, resulting in the …
