PROCESS FOR THE DESULFURIZATION OF HEAVY OILS AND BITUMENS
摘要
<p>The present invention relates to a process for desulfurizing bitumen and other heavy oils such as low API gravity, high viscosity crudes, tar sands bitumen, or shale oils with alkali metal compounds under conditions to promote in-situ regeneration of the alkali metal compounds. The present invention employs the use of superheated water and hydrogen under conditions to improve the desulfurization and alkali metal hydroxide regeneration kinetics at sub-critical temperatures.</p>
