Water gas is CO+H2 in the presence of coke.

What is wrong in this? Is it temperature? I think we use air also to speed up the reaction.

The process used the water-gas shift reaction:

CO + H2O -> CO2 + H2.

The process was discovered by passing high-pressure steam over hot coal.

Bosch Process A German chemist Bosch, prepared hydrogen on a large scale using inexpensive raw materials such as water and coal by passing steam over red-hot coke (carbon) at about 1000°C a mixture of carbon monoxide and hydrogen known as water gas is produced carbon monoxide is separated from the mixture by converting it to carbon dioxide.

Water gas, colorless poisonous gas that burns with an intensely hot, bluish (nearly colorless) flame. The gas is a mixture of carbon monoxide and hydrogen with very small amounts of other gases, e.g. , carbon dioxide, and is almost entirely combustible as a result. Water gas is so named because of the use of water (steam) in its preparation. This process involves treating white-hot hard coal or coke with a blast of steam; carbon monoxide and hydrogen are formed. The gas is manufactured in vast quantities for commercial use. It is of much importance in the preparation of hydrogen and as a fuel in the making of steel and in other industrial processes.

It is a mixture of hydrogen and carbon monoxide and is made by passing steam over incandescent coke.

Definitions of incandescent : Emitting light as a result of being heated.

"plumes of incandescent liquid rock"

Synonyms: white-hot, red-hot, burning, fiery, blazing, ablaze, aflame, glowing, aglow, radiant, bright, brilliant, luminous, sparkling, fervid, lucent, igneous

Examples of incandescent : The metal flakes heat up until they are incandescent and shine brightly or, at a high enough temperature, actually burn.

As it burns with a blue flame' it is also known as blue water gas.

The water gas is usually converted into carburetted ( enriched) water gas by passing it through a carburetter into which a gas oil is sprayed . It is usually, mixed with coal gas to form town gas the water gas is used in furnaces and for welding.

Water gas is formed by the steam passing through the red hot coal or coke in the furnace and it reacts to each other and to form a gas known as water gas. The gas consists of CO & H2O.

It forms the water gas this is widely used in the industrial applications for making steels&cast irons it is the by product of getting iron from ore in blast furnaces. It is poisonous gas cannot breath.

Carbon monoxide and hydrogen combination gives water gas at 147 KJ. It is also called as synthesis gas. It is a poisonous gas.

Dear friends.

The Water Gas is made by passing steam over a coke, containing carbon monoxide and hydrogen, a highly flammable and poisonous gas in industry it is used in production of steel.

Water gas is nothing but reaction between H2O and carbon at 147 kJ.
