Question

Which of the following is a process of thermochemical decomposition of organic materials by heat in the absence of oxygen?

• A. landfill
• B. Pyrolysis
• C. Incineration
• D. None of the above

Answer 1

The correct option is B Pyrolysis

Pyrolysis is a thermochemical decomposition of organic material at high temperatures in the absence of oxygen. It involves the change of chemical composition as well as physical state. It is an irreversible process. The process is used heavily in the chemical industry to produce charcoal, activated carbon, to convert biomass into biochar, to turn waste into safely disposable substances.

Thus, the correct answer is option B.
