Abstract
Hematite nanoparticles (23-150 nm) were obtained and dispersed in a hydrocarbon medium. The introduction of hematite nanoparticles at a concentration of 0.02 to 0.30 mass % into the oil residue during thermolysis allows increasing the yield of gasoline and reducing the yield of resins. The role of hematite is explained by its ability to selectively sorb resins and asphaltenes on its surface.
