<p>A method of desulphuration of heavy oil residues consists in heating the latter to a temperature of 190-200°C, passing through the heated heavy oil residues an electric current with a voltage of 4-20V and adding Fe2O3 and/or Pb3O4 and Ba(OH)2 at a ratio of components of 1-10:1-20 by weight respectively, the ratio between Fe2O3 and Pb3O4, in the case of their simultaneous use, being equal, respectively, to 2-9:1-5.</p> |
