During water-gas shift reaction

During water-gas shift reaction

Options

  1. ACarbon monoxide is oxidized to carbon dioxide.
  2. BWater is evaporated in presence of catalyst.
  3. CCarbon is oxidized to carbon monoxide.
  4. DCarbon dioxide is reduced to carbon monoxide.

Correct answer

A. Carbon monoxide is oxidized to carbon dioxide.

Step-by-step solution

The reaction between CO of syn gas and steam in presence of catalyst is called water gas shift reaction.

CO+H2O→CO2+H2OCO + {H}_{2}O \to {CO}_{2} + {H}_{2}O

This reaction increases the yield of hydrogen obtained from coal gasification reaction as shown below.

C+H2O⟶CO+H2⏟syngasC + {H}_{2}O ⟶ \mathop{\mathop{CO + {H}_{2}}_{⏟}}_{syngas}
