ABSTRACT:
This invention relates to a process for effectively and completely converting into a useful hydrocarbon oil comprising naphtha, kerosene and gas oil with high cracking rate, the tar-sand bitumen and the vacuum residues from various petroleum or origins which are difficult to treat in comparison with the ordinary crude oil and contain large amount of asphaltenes and resins according to the combined process of the thermal cracking and hydrocracking.
The present invention is useful to manufacture the pollution-free product oil from the tar-sand bitumen and the vacuum residues from the various petroleum origins with high desulfurization percentage of more than 90%. The product oil can be used as the superior fuel oil having less sulfur and metal contents and also as the starting material suitable for the secondary processing.
