Which one of the following statements explains the term pyrolysis?a)So...
Pyrolysis is a process of thermal decomposition of organic materials in the absence of oxygen. This process converts the organic material into gas, liquid, and solid residues. Pyrolysis is widely used for the treatment of different types of waste materials, including solid waste, biomass, and sewage sludge.
The following are the explanations of the term pyrolysis:
Process
Pyrolysis is a chemical process in which organic materials are decomposed by heating them in the absence of oxygen. During pyrolysis, the organic material is heated to a high temperature, which causes the breakdown of the chemical bonds within the material. This process results in the formation of volatile gases, liquid oils, and solid char.
Types of waste materials treated
Pyrolysis can be used to treat a wide range of waste materials, including solid waste, biomass, and sewage sludge. In the case of solid waste, the waste is heated in closed containers in an oxygen-free atmosphere. This process results in the formation of char, which can be used as a fuel, and gases, which can be used to generate energy.
Benefits of pyrolysis
Pyrolysis is an effective method for the treatment of waste materials. The process has several benefits, including:
• Reduced waste volume - Pyrolysis reduces the volume of waste materials by up to 90%.
• Energy recovery - Pyrolysis generates energy in the form of gases, which can be used to generate electricity or heat.
• Reduced greenhouse gas emissions - Pyrolysis produces fewer greenhouse gas emissions than traditional incineration methods.
In conclusion, pyrolysis is a process of thermal decomposition of organic materials in the absence of oxygen. This process is widely used for the treatment of different types of waste materials, including solid waste, biomass, and sewage sludge. Pyrolysis has several benefits, including reduced waste volume, energy recovery, and reduced greenhouse gas emissions.
