Abstract: A process to prepare a sweet crude from an ash containing and heavy fraction of a tar sand oil comprising supplying an atmospheric distillation bottoms of a tar sands originated feed to a vacuum distillation to obtain a vacuum gas oil and a vacuum bottoms and contacting the vacuum gas oil with hydrogen to obtain a sweet synthetic crude. The vacuum bottoms obtained are separated into an asphalt fraction comprising between 0.1 and 4 wt % ash and a de-asphalted oil and the asphalt fraction is fed to a burner of a gasification reactor to obtain a mixture of hydrogen and carbon monoxide on which a water gas shift reaction is performed. Hydrogen sulphide and carbon dioxide are separated from the shifted gas in an acid removal unit thereby obtaining crude hydrogen which is purified and used to obtain the sweet synthetic crude.
