In context with the industrial preparation of hydrogen from water gas (CO + H2), which of the following is the correct statement?
A.CO is oxidized to CO2 with steam in the✓ Correct
B.CO and H2 are fractionally separated using
C.CO is removed by absorption in aqueous
D.H2 is removed through occlusion with Pd.
Explanation
Preparation of hydrogen from Syn gas is called as Bosch process. It is prepared as- Syn gas on reaction with steam gives carbon dioxide and dihydrogen. 2 2 2 2 Syn gas CO(g) H (g) H O(g) CO (g) 2H (g) -> Carbon dioxide is removed by scrubbing the mixture with sodium arsenide solution. Therefore, option (a) is correct.
