Abstract
In Athabasca oil sands there is a fraction of poorly crystalline minerals tightly bound to humic matter. This fraction resists subsequent wetting by water and introduces serious problems in bitumen recovery when using water-based processes. In this study 29Si solid state magic angle spinning (MAS) NMR, infrared spectroscopy and transmission electron microscopy were applied to characterize these minerals isolated from Athabasca oil sands of estuarine and marine origin. It was demonstrated that poorly crystalline inorganic matter present in Athabasca oil sands is comprised of aluminosilicates, most probably allophane-like minerals. Humic matter could interact with this type of material through incorporation of an organic anion as a ligand to a metal ion, coulombic and van der Waals forces and hydrogen bonding.
