Consider the following statements about the process of Pyrolysis/Gasification.
1. In this process, waste is directly burned in the presence of excess air (oxygen) at high temperatures (about 800°C), liberating heat energy, inert gases, and ash.
2. Combustion results in 65–80% of the organic matter's heat content to hot air, steam, and hot water.
3. The steam generated, in turn, can be used in steam turbines to generate power.
Which of these statements is/are correct?
  • a)
    1 and 2 only
  • b)

°C to 1,200°C) to produce energy.

2. Pyrolysis/Gasification is a form of incineration that is highly efficient and environmentally sustainable.

3. The process can convert a wide range of waste materials into useful energy sources, including municipal solid waste, agricultural waste, and industrial waste.

4. Pyrolysis/Gasification can also be used to produce biochar, a type of charcoal that is used as a soil amendment to improve soil fertility and reduce greenhouse gas emissions.

5. The process is considered an alternative to traditional landfilling and incineration methods, as it has lower environmental impacts and can contribute to reducing carbon emissions.

6. Pyrolysis/Gasification is currently being used in several countries around the world, including China, Japan, Germany, and the United States, to manage waste and produce energy.

7. The process requires careful management to ensure that emissions are controlled and that the energy produced is safely and effectively used.

8. Pyrolysis/Gasification can also be used to produce synthesis gas, a mixture of carbon monoxide and hydrogen that can be used as a fuel or feedstock for the production of chemicals and other products.

  • Combustion/Incineration: In this process, waste is directly burned in the presence of excess air (oxygen) at high temperatures (about 800°C), liberating heat energy, inert gases, and ash. Combustion results in 65–80% of the organic matter's heat content to hot air, steam, and hot water.
  • Pyrolysis/Gasification Pyrolysis is a process of chemical decomposition of organic matter brought about by heat. In this process, the organic material is heated in the absence of air until the molecules thermally break down to become a gas comprising smaller molecules (known collectively as syngas).
  • After that, the gas is burned in internal combustion (I.C.) engine generator sets or turbines to produce electricity.
