Natural Resources Canada, CanmetENERGY Devon, 1 Oil Patch Drive, Devon, Alberta, Canada T9G 1A8 ABSTRACT: The stabilization of olefins in a thermally processed bitumen is a focal area for the development of bitumen partial upgrading technologies. Although a number of approaches have been proposed, including alkylation, oligomerization, and adsorption, hydrotreatment is still the most effective strategy for treating olefins in thermally cracked products such as coker naphtha. In our previous work, we studied the hydrogenation of model olefin compounds to understand their reactivity under mild conditions. This paper is a follow-up study focusing on the hydrotreatment of olefins in a thermally processed bitumen using a bench-scale continuous hydroprocessing unit. Two different scenarios were investigated: (1) hydrotreating the olefinrich light fraction (IBP-280 °C) of the thermally processed bitumen product and (2) hydrotreating the whole product. The cracked feedstock was prepared by processing oil sand bitumen under visbreaking conditions. It was found that on-specification product for olefin content (
