Correct Answer - Option 4 : Syn gas
Concept:
When the steam is passed over red hot coke, an equimolar mixture of CO and H2 is obtained.
H2O (g) + C → CO + H2
Steam Red Hot
The gaseous mixture thus obtained is called water gas or syn gas (synthesis gas)
Water gas is a mixture of carbon monoxide and hydrogen produced from synthesis gas. Synthesis gas is a useful product, but requires careful handling due to its flammability and the risk of carbon monoxide poisoning. The water gas shift reaction can be used to reduce the carbon monoxide while producing additional hydrogen, resulting in water gas.
A mixture of CO + H2 is called as water gas. Water gas is used with producer gas for the production of fuel gas. It is used to remove carbon monoxide from fuel cell applications. It is used to get pure hydrogen for the synthesis of ammonia.
Syn gas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide.
