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

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.

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.

Because of mond gas has obtained by passing air and a large amount of steam over waste coal at 650 degrees.

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.

The process used the water-gas shift reaction:

CO + H2O -> CO2 + H2.

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

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

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

The water gas contains that CO+H2 In presence of coke.

Mond gas is obtained by passing air and a large amount of steam over waste coal at about 650°C.
