Question

Difference between incineration and pyrolysis

Answer 1

Pyrolysis, is also called dry distillation, thermal decomposition or carbonization, which refers to the process of heating the organic matter in the absence of oxygen and making it decomposition. So pyrolysis utilizes thermal instability of the organic matter, in the absence of oxygen condition, and utilizes thermal energy to make the valency of the compound break from large molecular weight of organic matter into small molecular weight of fuel gas, liquid (oil, grease, etc. ) and coke whereas Incineration is an exothermic process while pyrolysis is an endothermic process, which needs to absorb large amount of heat.

Answer 2

Difference between incineration and pyrolysis is given below.

Incineration:

• Incineration is a process of waste treatment.
• And it involves the combustion of waste materials.
• In this process, waste material burning under suitable conditions.
• It is an irreversible reaction.
• The biomedical wastes and hazardous wastes are burning under suitable conditions until to produce ash.

Pyrolysis:

• Absence of oxygen, the decomposition of organic substances at elevated temperature.
• It is a reversible reaction.
• The process involves in changing the composition of chemical substances.
• Example: Charring of wood.
