The objective of this research is to determine the relationship between the size and shape of coal and petroleum macromolecules and their diffusion rates i.e., effective diffusivities, in catalyst pore structures. This quarter, three petroleum and two coal asphaltenes were prepared from petroleum asphalts and coal derived solids separately by solvent extraction
