Commercial scale production of hydrogen from iron-steam reaction represented by, 3Fe + 3H2O = Fe3O4 + 4H2, is not practised, as it is __________________?
Correct answer: D. All A , B. and C
- A. A slow reaction
- B. A discontinuous reaction (requiring regeneration of iron by water gas intermittently)
- C. Still in development stage (by employing fluidised bed technique)
- D. All A , B. and C
Explanation
The iron-steam process is unsuitable for continuous commercial hydrogen production because the iron must be regenerated, making the operation cyclic and discontinuous, while the reaction is relatively slow. Fluidised-bed development was intended to address these limitations, so the combined choice is applicable.
