step 1

  • Coke burns in the hot air forming carbon dioxide 

  • The reaction is exothermic so it gives off heat, heating the furnace

carbon + oxygen → carbon dioxide

New cards

step 2

  • At the high temperatures in the furnace, more coke reacts with carbon dioxide forming carbon monoxide

  • Carbon dioxide has been reduced to carbon monoxide

carbon + carbon dioxide → carbon monoxide
