Abstract

<PICT:0628417/III/1> In a continuous process for producing hydrogen by reacting steam with a metalliferous reducing agent, e.g. iron, ferromanganese, ferrochrome, ferrous oxide, mixtures of copper oxides and iron, or manganese oxides, of the type in which the reducing agent is maintained as a dense fluidized bed in a reactor, while spent reducing agent is continuously withdrawn, passed to a regenerator wherein it is regenerated as a dense fluidized bed, and recycled to the reactor, the regenerator is at a higher level than the reactor, the reactor is at a higher pressure than the regenerator, and the regenerated reducing agent is recycled through a standpipe as a dense fluidized column whose fluistatic pressure is sufficient to compensate for the pressure differential between reactor and regenerator. Preferably the regenerator is at a higher temperature than the reactor, and the heat for hydrogen generation is provided by sensible heat of the recycled reducing agent. Superheated steam with ferrous oxide from standpipe 40 pass through pipe 1 to dense bed of generator 10, at 800-1500 DEG F. and up to 100 atmospheres or higher pressure, and hydrogen is withdrawn through separator 12, while spent ferrous oxide is returned through reverse standpipe 18 as a phase of progressively decreasing density to regenerator 30 at 800-1700 DEG F., and atmospheric pressure either through aerated line 22 or branch 18a. A fuel and/or regenerating agent, e.g. methane, water gas, impure hydrogen, liquid hydrocarbons, or fluidized solid such as coal or coke with air or oxygen is supplied at 28 and regenerator 30 may have countercurrent flow by use of two or more superimposed dense beds 26, 26a with overflow 40a, while more fuel and/or regenerating agent may be supplied at 52. Regenerated reducing agent is returned to fluidized standpipe 40 which may be 50 to 200 feet high to give the necessary pressure difference between the generator and regenerator. Specifications 578,323 and 586,914 are referred to.
