Carbonization is the complex process of concentrating and purifying carbon by denaturing organic matter with heat in the presence of little to no oxygen. In the context of coal, carbonization consists of four coincident and partly competing steps.

What is an example of carbonization?

A very common example of carbonization are fossil plants, where only a thin carbon layer is left on a piece of shale. In the Carboniferous time period, fast fern forests created miles of carbon, which we mine today as coal. Another, more recent example is the fossilized feathers found on dinosaurs in China.

What is carbonization process of coal?

Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. ... A gaseous by-product referred to as coke oven gas (COG) along with ammonia (NH3), water, and sulphur compounds are also thermally removed from the coal.
