FIELD: oil and gas industry.
SUBSTANCE: invention refers to oil stock quality improvement. This invention relates to method of improvement of refining residues quality including residues hydrocracking at the first stage (14) of reaction with formation of flow passing from the first stage; hydrocracking of fraction of asphalt-free oil at the second stage (22) of reaction with formation of flow passing from the second stage; supply of flow passing from the first stage and the flow passing from the second stage to separating system (26); fractioning of flow passing from the first stage and the flow passing from the second stage in separating system (26) with extraction of at least one distillate hydrocarbon fraction and residual hydrocarbon fraction; and supply of residual hydrocarbon fraction to the plant (32) of grout deasphalting obtaining fraction of asphaltens and fraction of asphalt-free oil.
EFFECT: increasing general conversion of residue.
