Hydroprocessing of a North Gujarat Crude oil (of Indian Origin) in a light gas oil solution was carried out over a commercial hydrotreating catalyst at a temperature between 300 to 450°C and a pressure of 6.8 to 20 Mpa in a laboratory reactor. About 30 to 60% of the long residue (365°C + cut) in the solution is converted to light distillates. Simultaneous removal of sulfur, nitrogen, oxygen and metals took place in substantial quantities.
