With increase in the time of carbonisation at a particular temperature (say 1000°C), the ______________ percentage in coke oven gas increases?
Correct answer: A. Hydrogen
- A. Hydrogen
- B. Methane
- C. Unsaturated hydrocarbons
- D. All A., B. and C.
Explanation
As carbonisation continues at high temperature, methane and unsaturated hydrocarbons undergo further cracking, while hydrogen formation increases. Therefore, hydrogen becomes a larger percentage of coke-oven gas.
