ABSTRACT:
A process comprising passing a first stream comprising residual oil and hydrogen downwardly through a zone containing hydrodesulfurization catalyst under hydrodesulfurization conditions until said catalyst is deactivated. Subsequently, passing a second stream of residual oil and hydrogen upwardly through the deactivated hydrodesulfurization catalyst under thermal cracking conditions, including a temperature above the hydrodesulfurization temperature.
