NO-4-27580C/YT/82 ABSTRACT OF THE DISCLOSURE 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 first 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 to 1,000°C to effect roasting and gasification of iron sulfide in the catalyst.
