Analysis of asphaltenes adsorption on surfaces using QCM-D

The adsorption of asphaltenes in crude oil to different surfaces represents an  important issue for the petrochemical industry. QCM-D technology can be used to  evaluate different approaches to solve such problems. In particular, the ability of QCM-D technology to monitor various structural arrangements of adsorbed materials can be used to understand how asphaltenes adsorb to surfaces.

In this application note:

Asphaltene adsorption under various conditions has been analyzed and quantified. The note includes asphaltene–surface interaction results for:

  • Different hydrophilic surface materials (e.g. SiO₂, Al₂O₃, TiOₓ, FeOₓ)

  • Asphaltenes from different crude oil origins

  • Solvent conditions with varying asphaltene stability (e.g. toluene, heptane/toluene mixtures)
