    摘要： A process for simultaneously cracking a heavy hydrocarbons to form light oil and producing hydrogen is described, which comprises (1) a first step wherein steam and heavy hydrocarbons are simultaneously contacted with a catalyst in a reduced state, containing iron in the form of iron oxide, to produce hydrogen, cracked gases and cracked light oils, to convert the reduced-state catalyst into an oxidized-state catalyst, and to deposit coke on the catalyst, (2) a second step wherein the oxidized-state catalyst with coke deposited thereon is contacted with an oxygen-containing gas to partially combust the coke on the catalyst, to convert the oxidized-state catalyst into a reduced-state catalyst, and to fix a sulfur compound contained in the coke as iron sulfide with a part of the reduced-state catalyst; and (3) a third step wherein catalyst obtained from the second step, the major portion of the catalyst being recycled between the first step and second step, is contacted with an oxygen-containing gas at a temperature of from 600.degree. to 1,000.degree. C. to effect roasting and gasification of iron sulfide in the catalyst.

    摘要： A process for processing a sulfur-containing heavy oil, which comprises:in a first zone, catalytically cracking a sulfur-containing heavy oil in the presence of fluidized catalyst particles containing about 30 to 60 wt % Fe to thereby convert the heavy oil to a light oil, deposit sulfur-containing coke on the catalyst particles, and partially fixing the decomposed sulfur compounds 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; andin 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.
