Question

What is carbonization? Explain process of formation of coal. brief explanation plz ​

Answer 1

Answer:

Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making.

Answer 2

Answer:

Hey mate,

Your answer is as follows:

Carbonization is done to obtain charcoal by heating solid biomass in the absence of air or oxygen. Carbonization is the term for the conversion of an organic substance into carbon or a carbon-containing residue through pyrolysis or destructive distillation.

The process that creates coal varies slightly in different areas depending on the plants and conditions that are present, but the overall process is similar. There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. To form coal, the following steps are followed.

1. Plant matter in mires and wetlands, such as ferns, shrubs, vines, trees, and algae dies and accumulates on the surface. Initially the organic matter is decomposed by bacteria, yielding carbon dioxide and methane.

2. The plant matter becomes buried, and are no longer exposed to air. Anaerobic bacteria then starts to decompose the material. Burial and accumulation can occur for several thousands of years, producing several meters of partially decayed plant matter known as peat.[6]

3. When this peat is deeply buried, water and other compounds is squeezed out from the increasing pressure and the lowest quality of coal, lignite, begins for form.

4. Continued burial, resulting in increasing pressures and temperatures, causes this low quality lignite coal to be transformed into higher quality "black coals". First lignite becomes sub-bituminous coal, then bituminous coal, and finally the highest quality anthracite coal. As these transformations occur, the amount of water and other compounds in the coal decreases and the coal becomes more dense. Along with this comes a higher carbon concentration.
