We present here an overview of the results of our experimental studies of asphaltene diffusion. The implications of these results on our understanding of the asphaltenes structure and for resid upgrading reactor design are discussed.
Use of the simple perturbation molecular orbital (PMO) method allows the first-order estimation of energies of formation (I$ of polycyclic aromatic hydrocarbons (PAH) as well as their localization (EL) and bislocalization (E,,) energies. These calculations give theoretical support to experimental ev
