Abstract
A process for the preparation of synthetic bitumen from asphaltenes and oil, characterized in that asphaltenes are obtained from a residual oil by application of a precipitant and by separation of the precipitated asphaltenes, the concentrated asphaltenes are added to a residual oil, Oil is distilled from the resulting mixture, and synthetic bitumen is obtained as a product from the bottoms.
