THE IRON OXIDE CATALYST USED FOR THERMOLYSIS OF HEAVY CRUDE HYDROCARBONS Russian patent published in 2012 - IPC B01J23/745 B01J23/881 C10G11/08 C10G51/04 C10G49/02 

FIELD: petrochemistry.

SUBSTANCE: invention relates to the field of catalysis and can be applied as a catalyst in the process of thermolysis of heavy crude and fuel-oil residuals; the method describes the iron oxide catalysts used for thermolysis of heavy crude hydrocarbons which allows to increase the output of light fractions without application of steam and hydrogen; the above catalyst represents the microspheric magnetic product substracted from flue dust received in the process of burning of powdered brown and black coal with the fraction within the range of 0.05-0.4 mm 80-90 % consisting of the iron oxide (silicon oxide, aluminium, calcium, magnesium, natrium, kalium, manganese, sulphur make up the rest of the composition) therein the iron oxide is constituted by two iron-containing phases: 13.0- 34.5 % of the mass - ferromagnetic spinel and 35.0-63.0 % - hematite.

EFFECT: catalyst with advanced activity in the process of heavy crude hydrocarbons cracking.
