- Summary:
- The aim of this paper is to understand the soot dispersion mechanism in used lubricants. The efficiency of dispersant additives and polymers on particle stabilization in a lubricating oil is investigated by adsorption and sedimentation experiments. Carbon black particles are chosen as a model for soot present in lubricants. Comparison between diesel soot and carbon black, using Transmission Electronic Microscopy photographs, shows that both kind of particles exhibit a fractal structure with similar aggregate size. Sedimentation experiments in oil show that polymers and ashless dispersants stabilize particles over a critical concentration. Adsorption isotherms in oil are carried out in order to determine the action mechanism of dispersant against particles aggregation
