Question

Water gas is also called as syngas
A. True
B. False

Answer 1

We know a mixture of carbon monoxide and hydrogen is known as water gas. Water gas is used for production of hydrogen. Since both constituents of water gas are gases that are combustible, they could be used as a source to gas turbines for production of water.

Complete step by step answer: Let us know that syngas is a mixture of carbon monoxide and hydrogen that is the product of steam or oxygen gasification of organic material like biomass. After clean up, syngas can be used in production of organic molecules such as synthetic natural gas or liquid biofuel like synthetic diesel.
We must know the term Syngas is used for a mixture of combustible gases. A mixture of syngas would consist of only hydrogen and carbon monoxide, with the possibility of having carbon dioxide sometimes. If the gasification product contains a significant amount of non-combustible gases such as nitrogen and carbon dioxide, we call the mixtures as 'Producer Gas'.
We can say that water gas is an older terminology. Based on composition, both syngas and water gas contain the same components: Hydrogen and carbon monoxide, with or without some amount of carbon dioxide. However, the production of water gas and syngas is different.
We can obtain water gas by passing steam over red hot coke.
Syngas is produced industrially by steam reforming of natural gas, which involves catalytic decomposition of methane in steam to yield the resultant mixture along with the traditional coal gasification and various other techniques.
Water gas is called as syngas is false.
$\therefore$, The option (B) is correct.

Note: We must remember that the producer gas is a mixture of hydrogen, methane and carbon monoxide that are combustible gases and non-combustible gases such as carbon dioxide and nitrogen. Like to syngas, producer gas is also produced by gasification of carbonaceous material like coal or biomass. When atmospheric air is used as a gasification agent, the producer gas majorly comprises carbon monoxide, hydrogen, nitrogen, carbon dioxide and methane. Water gas shift reaction also known as Lowe's gas process is used to remove carbon monoxide from water gas to get pure hydrogen for the applications of fuel cells.
