Which adsorbent is used for removing sulphur compounds (S Q, H2S, RSH etc.) removal from coke oven gas in by-products recovery plant ?
Correct answer: D. Bog iron (i.e., moist ferric hydroxide)
- A. Silica gel
- B. Diatomaceous earth
- C. Basalt
- D. Bog iron (i.e., moist ferric hydroxide)
Explanation
Moist ferric hydroxide, or bog iron, absorbs hydrogen sulphide and other sulphur compounds by forming iron sulphides. Silica gel and diatomaceous earth are used mainly for drying or filtration, not this desulphurisation duty.
