Question

Carbon deposition reaction taking place in ______.

विकल्प

• Reduction zone

• Central zone

• Fusion zone

• Combustion zone

Answer 1

Carbon deposition reaction taking place in Central zone.

Explanation:

\[\ce{Fe + 2CO -> CO2 + C + Fe}\] (900 – 1200°C) iron act as catalyst.

A sufficient amount of heat is involved in the central zone of the blast furnace above 800°C, which decomposes part of the carbon monoxide in carbon.

\[\ce{2CO -> CO2 + C}\]
