A process is described for cracking a heavy hydrocarbon to form a light oil and for producing hydrogen by the use of a catalyst containing at least 30 wt % Fe which comprises a first step wherein steam and heavy hydrocarbon are simultaneously contacted with the catalyst in a reduced state to produce hydrogen, cracked gases, and a cracked light oil, to oxidize the reduced-state catalyst, and to deposit coke on the catalyst; and a second step wherein the oxidized-state catalyst on which said coke is deposited is contacted with an oxygen-containing gas insufficient for achieving complete combustion of the coke, to thereby partially combust the coke and regenerate the catalyst to a reduced state.
