Processing of tar sand bitumens. I. Thermal cracking of Utah and Athabasca tar sand bitumens. [Yields and properties of products]
Thermal cracking characteristics of three Utah and one Athabasca tar sand bitumen were studied and results are discussed in terms of bitumen properties and composition. Bitumen character resembles representative petroleum distillation residues, but tar sand bitumens differ principally in their higher heteroatom content and in their higher concentrations of high molecular weight compounds. The thermal cracking and compositional features of Utah samples are compared with the Athabasca sample for which considerably more processing information is known. Elemental analysis, physical properties, and easily determined compositional features of the liquid products are presented. This information provides a basis for evaluation of thermally derived tar sand liquids and for comparison with coal derived liquids and shale oil.
