The relationship between the diffusion coefficient of asphaltenes and pore size was studied experimentally using track-etched mica membranes. The asphaltenes were extracted from Kuwait atmospheric bottoms using criteria of n-pentane insolubility and tetrahydrofuran solnbility at 25°C. Data were obta
