Expert Answer
This process requires heat (endothermic). So the steam should not be passed over hot coke as it may cool down the coke. So after some time steam is alternatively replaced by the air stream.
The reaction is:
C(white hot) + H2O(steam) → CO + H2
If steam is passed for a long time, it may react with carbon monoxide (CO) and make carbon dioxide which is not a required product.
