Isolation, characterization and modification of clay solids from oil sand wastes

摘要

For the past several years, we have been exploring the possibility of using oil sand industry wastes, such as: coke, fly ash and fine tailings as resource materials for several potentially marketable products. In this investigation we have developed a technically feasible fractionation methodology to separate clay solids from oil sands coke fly ash for potential use as polymer reinforcements after surface modification. The separated clay fraction has been characterized by elemental analysis, X-ray diffraction, XPS, SEM, infrared spectroscopy, and surface area measurements.
