CATALYST SYSTEM IN THERMOLYSIS OF HEAVY OIL STOCK AND OIL EXTRACTION AND REFINING WASTES Russian patent published in 2014 - IPC B01J23/745 B01J23/881 C10G49/02 

FIELD: chemistry.

SUBSTANCE: magnetic product consists of iron oxide Fe₂O₃ and/or Fe₃O₄ particles sorted according to size in the range of 0.002-2.5 mm in form of powder and/or a solution of a magnetic product in a hydrocarbon solvent in concentration of 1-50%, which are mixed until achieving complete homogenisation at temperature of 120-200°C in a ratio ranging from 20:1 to 10:1 by weight with a prepared mixture of sodium chloride NaCl or potassium chloride KCl or lithium chloride LiCl or a mixture thereof and aluminium chloride AlCl₃, which is prepared by mixing starting salts in equimolar ratios and then heating the mixture to the melting point thereof in the range of 150-200°C.

EFFECT: high destructive activity with respect to high-molecular weight hydrocarbon compounds of the heavy oil stock.
