Oil-soluble organic-inorganic fused slurry phase hydroprocessing catalysts for heavy oils and residues are prepared at supercritical conditions. The hydrodemetallisation, hydrodesulfurisation, asphaltene conversion and hydrocracking activities of a residue having a high percentage of metals, sulfur and asphaltene have been tested in an autoclave batch reactor. The different organic compounds are used to modify the solid fused material (catalyst). The effect of the concentration of modifier on the hydroprocessing and hydrocracking reactions has also been investigated.
