NO-4-23292C/80 ABSTRACT OF THE DISCLOSURE A process for processing a sulfur-containing heavy oil, which comprises: in a first zone, catalytically cracking a sulfur con- taining heavy oil in the presence of fluidized catalyst particles containing about 3 0 to 60 wt % Fe to thereby convert the heavy oil to a light oil, deposit sulfur containing coke on the cat- alyst particles, and partially fixing the decomposed sulfur com- pounds with the reduced iron contained in the catalyst particles as iron sulfide; in a second zone, contacting the catalyst from the first zone with an oxygen containing gas in an amount less than that theoretically required to thereby partially combust the coke on the catalyst, reduce the iron in the catalyst, and fix the sulfur compounds contained in the coke as iron sulfide; and in a third zone, contacting the reduced catalyst from the second zone with steam in a fluidized manner to produce hydrogen and hydrogen sulfide and to convert the reduced iron and iron sulfide in the catalyst to iron oxides, with the iron oxide-containing catalyst obtained in the third zone being recirculated into the second zone to be reduced and a part of the reduced-state catalyst obtained in the second zone being recirculated into the first zone.
