Structure And Interaction Of Asphaltene Colloids In Organic Solvents,ine mixtures. In the dilute concentrations regime, the data were analyzed using a self-consistent algorithm, neglecting the interparticle interactions. The results suggest that the asphaltene colloids are approximately spherical, but with an appreciable size polydispersity. For the moderate to high

Diffusion And Structural Studies Of Asphaltenes And Their Implications For Resid Upgrading,r understanding of the phenomena such as asphaltene structure, colloidal nature and mechanism of asphaltene diffusion through porous systems is desirable. The diffusive behavior showed that asphaltenes are polydisperse entities consisting of many components with a broad range of transport coefficien

The Study Of Molecular Attractions In The Asphalt System By Solubility Parameter,ecular forces can be estimated by the solubility parameter. Both one-component and three-component solubility parameters are used to study the molecular attraction within the asphalt system. In one-component solubility parameter study, three colloidal types of asphalts and corresponding asphaltenes

Solvation of Ratawi Asphaltenes in Vacuum Residue,(heptane insolubles) are polydispersed spheres solvated by the nonasphaltene fluid at 93 °C. The Pal-Rhodes equation attributes the non-linear dependence of the relative viscosity on asphaltene concentration to solvation and polydispersity effects. In other words the direct interactions between the
