FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method for removing asphaltenes and metals from heavy oil stock. The method of high-temperature deasphalting and demetallization of heavy oil stock is performed as follows. Heavy oil or masut is passed through a fixed bed of adsorbent at the temperature of 300-600°C at the stock feed rate through the adsorbent of 0.5-2 g-stock / g-adsorbent / hr in the presence of hydrogen supplied at the pressure of 4-7 MPa, the method being characterized in that an adsorbent consisting of gamma-alumina obtained by means of template synthesis, containing macropores that form the regular three-dimensional structure, is used, wherein the proportion of the macropores with a size ranging from 50 nm to 500 nm is not less than 30% of the total pore volume.
EFFECT: invention is an economical method of obtaining liquid oil products with the low content of metals and asphaltenes.
