METHOD OF EXTRACTING METALS FROM STREAM RICH IN HYDROCARBONS AND CARBON-CONTAINING RESIDUES Russian patent published in 2015 - IPC C10G47/26 C10G49/12 B01J37/08 B01J37/12 

FIELD: chemistry.

SUBSTANCE: invention relates to extraction of metals from a stream rich in hydrocarbons and carbon-containing residues using a treatment area. The method includes the following steps: feeding said stream for primary treatment, which is carried out in one or more steps, where said stream is treated in the presence of a diluent in a mechanical treatment apparatus at temperature of 80-180°C, preferably 100-160°C, and is divided into a liquid phase and a solid phase to obtain a purified product, primary consisting of liquids, and a condensed residue (oil cake); optionally drying the separated condensed residue to remove therefrom a hydrocarbon component with a boiling point lower than 300-350°C; feeding the condensed residue, optionally dried, for secondary heat treatment, which includes: flameless pyrolysis of the condensed residue, carried out at 400-800°C; oxidising the pyrolysis residue, carried out in an oxidative medium and at 400-800°C, preferably 500-700°C, to obtain a product primarily consisting of sulphides/inorganic oxides of metals; selectively extracting metal components from the product obtained at secondary heat treatment step.

EFFECT: extracting and recycling the active component of an operating catalyst.
