摘要：

Tar sand samples from the Whiterocks deposit, located in the Uinta basin of Utah, were obtained from three different locations. Bitumen separation from each of these samples was accomplished by the Dean-Stark toluene extraction method and the physical and chemical properties of the resulting bitumens were determined. Further, each bitumen sample was fractionated by the modified Saturates, Aromatics, Resins, and Asphaltenes method, and the separated fractions from one of the bitumens were characterized by Fourier transform infrared transmission and specular reflectance techniques. The results show that there are very small differences among them and that they contain relatively low amounts of asphaltenes. The low asphaltenes content of the Whiterocks bitumen is considered to be an advantageous feature for the development of subsequent upgrading process strategies. Finally, properties of the Whiterocks bitumen were compared to the bitumens extracted from the other deposits of the Uinta basin, viz., Asphalt Ridge and Sunnyside.
