Title: Process for generating hydrogen from heavy oil or hydrocarbons

Abstract

The present invention provides a steam reforming process for heavy oil or hydrocarbons using a circulating fluidized bed reactor, the process having a reforming step and a regeneration step, wherein the reforming step and the regeneration step comprise a bubbling fluidized reactor containing a fluidizable nickel-containing reforming catalyst and produce hydrogen as a product of the reforming bed. The API gravity of the feedstock may be between −11 and 54, preferably between −11 and 20. The present invention also provides a fluidized bed hydrocarbon steam reforming process using a regenerable catalyst to produce hydrogen, wherein a circulating bed reactor is operated in an alternating manner, switching between two steps: reforming and regeneration; using a mixture of a fluidizable solid and a fluidizable nickel-containing reforming catalyst; producing hydrogen as a product of the reforming step with a minimum hydrogen content of 25 volume percent, preferably at least 60 volume % and more preferably at least 70 volume percent on a dry weight basis.
