What is the correct sequence of concentration of various components of producer gas?
(A) CH₂
(B) CO₂
(C) CO
(D) N₂
Choose the correct answer from the options given below:

Correct option is B

The typical concentration of components in producer gas (a fuel gas made from carbonaceous materials through gasification) is:
1. (D) N₂ (Nitrogen): 50-60%
2. (C) CO (Carbon Monoxide): 20-30%
3. (B) CO₂ (Carbon Dioxide): 5-10%
4. (A) CH2 (Methane): 2-5%
Hence, the correct sequence is N₂ > CO > CO₂ > CH2.
Information Booster: · Producer gas: A combustible gas mixture produced from coal or biomass gasification, used primarily for industrial heating.
· Nitrogen (N₂): Constitutes the largest proportion, but it is inert and doesn't contribute to the heating value.
· Carbon Monoxide (CO): Provides most of the energy in producer gas as it is a combustible gas.
· Carbon Dioxide (CO₂): A non-combustible gas that lowers the overall efficiency of the gas.
· Methane (CH2): A smaller but useful component, also contributing to the heating value of the gas.
Additional Knowledge: · Gasification: A process that converts organic or fossil fuel-based carbonaceous materials into gases, including carbon monoxide, hydrogen, and carbon dioxide.
· Industrial Uses: Producer gas is used in internal combustion engines and for furnaces due to its combustible nature.
