Industrial fuel gases are synthesized through various chemical reactions to serve specific heating and synthesis applications. Among these, fuel gases are categorized by their combustible and non-combustible constituent gases. Which of the following correctly describes the chemical composition of Water Gas?

A mixture of carbon monoxide ( $CO$ ) and hydrogen ( $H_2$ )Cevap
B
A mixture of carbon monoxide ( $CO$ ) and nitrogen ( $N_2$ )
C
A mixture of methane ( $CH_4$ ) and carbon dioxide ( $CO_2$ )
D
A mixture of propane ( $C_3H_8$ ) and butane ( $C_4H_{10}$ )

Cevap

The chemical composition of Water Gas is a mixture of carbon monoxide (

CO

) and hydrogen (

H_2

Water Gas is an important industrial synthesis gas formed by reacting steam with red-hot carbon at elevated temperatures, yielding an approximate 1:1 mixture of carbon monoxide (

CO

) and hydrogen (

H_2

). It has high calorific value and serves as a precursor in methanol synthesis and fuel cells.

Adım Adım Çözüm

Identify the industrial synthesis reaction for Water Gas

Passing steam (

H_2O

) over red-hot coke (

C

) at high temperatures yields

C + H_2O \rightarrow CO + H_2

This endothermic reaction produces an equimolar mixture of carbon monoxide and hydrogen.

Distinguish Water Gas from other industrial fuel gases

Water Gas consists of

CO + H_2

, whereas Producer Gas consists of

CO + N_2

(formed by passing air over hot coke).

Clear differentiation of fuel gases by their constituent components is essential for industrial synthesis.
