In the manufacture of hydrogen from water gas ( ( CO + H ₂ ) ), which of the following is correct statement?
Options
- A( CO ) is oxidized to ( CO ₂ ) with steam in the presence of a catalyst followed by absorption of ( CO ₂ ) in
- B( CO ) and ( H ₂ ) are separated based on difference in their densities.
- CHydrogen is isolated by diffusion.
- D( H ₂ ) is removed by occlusion with pd.
Correct answer
A. ( CO ) is oxidized to ( CO ₂ ) with steam in the presence of a catalyst followed by absorption of ( CO ₂ ) in
Step-by-step solution
In the manufacture of hydrogen from water gas ( ( CO + H ₂ ) ) ( CO + H ₂+ H ₂ O CO ₂+2 H ₂ ) ( CO ) is oxidized to ( CO ₂ ) with steam in the presence of a catalyst followed by absorption of ( CO ₂ ) in alkali. ( 3 CO ₂+4 ~N a 2 Na ₂ CO ₃ )
