The process of hydrodesulfurization is developed so that it can be used after the de-asphalting of the residue with light gasoline. Heavy residual products of sulfur and high sulfur crude petroleum is de-asphalted with light gasoline (virgin gasoline) in standard extraction columns at a temperature of 140-190 deg. C and a dilution ratio of 3.51 to 51. The content of ash in the de-asphalted oil compared with the feed stock will be 2-4 times less and its coking tendency about 1.5-2 times less. In addition, 2-7 percent of the feed is in the form of a new product - petroleum asphaltite - containing 60-80 percent asphaltenes, 10-20 percent of resin and 10-20 percent of oil. The asphaltite is easily powdered and does not agglomerate in storage.
