Which one of the following statements about PYROLYSIS, which is a process for solid waste treatment is incorrect?
-
- It converts the waste into solid, liquid and gas of which the resultant liquid and gas can be used to produce energy.
- The process occurs at a temperature above 430°C at atmospheric pressure.
- The process occurs under high pressure at temperature above 430° C.
- It is a thermochemical decomposition of organic waste
- It converts the waste into solid, liquid and gas of which the resultant liquid and gas can be used to produce energy.
Correct Option: B
Pyrolysis is a thermo-chemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen). Pyrolysis generally takes place well above atmospheric pressure at temperatures exceeding above 430 °C.
