Abstract. The transformation of vegetable matter into peat and coal is commonly regarded as proceeding in two steps, called the biochemical and physicochemical stage of coalification (Stach et al. 1982), respectively. Other terms, such as "first and second phase" (Mackowsky 1953), or "diagenetic and metamorphic stage" (Teichmüller 1962 ...

The conversion of dead vegetation into coal is called coalification. At various times in the geologic past, the Earth had dense forests in lowlying wetland areas. In these wetlands, the process of coalification began when dead plant matter was protected from biodegradation and oxidation, usually by mud or acidic water, and was converted into peat.

When these died, they too got covered. Sometimes earthquake and volcanoes buried entire forests deep down in the earth. The high temperature and high pressure inside the earth slowly converted the buried vegetation into coal. A coal contains mainly carbon. Thus, this slow process of conversion of wood into coal is called carbonization.

The most common biomass materials used for energy are plants, wood, and waste. These are called biomass feedstocks. Biomass energy can also be a nonrenewable energy source. Biomass contains energy first derived from the sun: Plants absorb the sun's energy through photosynthesis, and convert carbon dioxide and water into nutrients (carbohydrates).

Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization . Carbonization differs from coalification in that it occurs much faster, due to its reaction rate being faster by many orders of magnitude.
