Question

The other name for syngas is:
A. Producer gas
B. Water gas
C. tear gas
D. Fuel gas

Answer 1

Hint: Synthesis gas or syngas is defined as a gas where hydrogen and carbon monoxide are the main components. Row syngas mainly consists of carbon dioxide and water as the main components.

Complete step by step answer:
Syngas is the abbreviation used for synthesis gas which is formed by the mixture of carbon monoxide, carbon dioxide and Hydrogen. The production of syngas is done by gasification of fuel containing carbon to form gaseous products which have some heating value.
The gasification is the technique which is used to convert any compound carrying a carbon into a long chain hydrocarbon.
The syngas is commonly known as water gas. The water gas is a mixture of carbon monoxide, hydrogen which is produced by passing steam on the coke which is red hot.
The reaction is shown below.
$C + {H_2}O \to CO + {H_2}$
This reaction is an endothermic reaction as heat is absorbed during the reaction. The product which is formed has lower calorific value than the coal gas. Thus the resulting gas is passed through the heater retort where oil is sprayed externally. As a result a mixed gas is formed which is known as carbureted water gas.
Thus, the other name for syngas is water gas.
So, the correct answer is “Option B”.

Note:
The syngas contains 50 % of energy density of natural gas therefore, it cannot be burnt directly thus used as a fuel. The other application of syngas is that it is used in production of chemicals.
