In context with the industrial preparation of hydrogen from water gas (CO + H2), which of the following is the correct statement?
Correct answer: D. CO is oxidized to CO2 with steam in the presence of a catalyst followed by absorption of CO2 in an alkaline solution
- A. CO and H2 are fractionally separated using Copper Chloride solution
- B. CO is removed by absorption in aqueous Cu2Cl2 solution
- C. H2 is removed through occlusion with Pd
- D. CO is oxidized to CO2 with steam in the presence of a catalyst followed by absorption of CO2 in an alkaline solution
Explanation
This describes the water-gas shift reaction. The initial mixture is treated with steam over a catalyst to convert the toxic CO into CO₂, producing more H₂. The CO₂ is then easily removed by scrubbing the gas mixture with an alkaline solution, leaving purified hydrogen.
