FIELD: oil extraction and refining.
SUBSTANCE: invention relates to a method for deasphalting hydrocarbon raw materials, for which heavy oil is used, consisting in adding an organic solvent, hexamethyldisiloxane to it, mixing, filtering the hydrocarbon raw materials dissolved in the organic solvent from the precipitated resinous-asphaltene substances and cleaning the hydrocarbon raw materials from the organic solvent by distillation. Mixing is carried out on an upper-drive mixing device at the following ratio of components, wt. %: hexamethyldisiloxane 92; heavy oil the rest.
EFFECT: more complete removal of resinous-asphaltene substances from the composition of hydrocarbon raw materials, more significant reduction in its viscosity and better desulfurization at lower energy costs.
