Coal and biomass are important feedstocks for carbon energy from thermochemical conversion process. Fully understanding the analytical technology that characterizes the changes in physicochemical properties and structural characteristics of coal and biomass during the thermochemical reactions is a key prerequisite for the realization of appropriate utilization of energy fuels.

Coal began to take the place of wood as a heating and energy source because it was easy to transport, and because it held more energy than its predecessor. As technology advanced, the potential of oil began to be better understood as well, and by the end of the 19th century, coal mines and crude oil wells were the driving source of energy for a ...

Carbonization Process. In the carbonization process, coal, as a result of the thermal effect in an inert atmosphere and slow heating rate, undergoes structural modifications that produce a raw gas (known as COG, which amounts to around 25wt% of the coal charged) and a molecular rearrangement of the carbon cluster, the result of which is a highly carbonaceous and graphitizable coke.

The water remaining in the wood to be carbonised, must be evaporated in the kiln or pit and this energy must be provided by burning some of the wood itself which otherwise would be converted into useful charcoal. The first step in carbonization in the kiln is drying out of the wood at 100°C or below to zero moisture content.

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.
