Carbonisation is the process of decomposition of an organic compound until it is reduced to carbon. Wood is an organic matter and when it is decomposed, it turns into coal which is an amorphous form of carbon. The process of conversion of wood into coal is called carbonisation.

Researcher Patrick G. Hatcher wants to know how. "One problem with studying how wood converts to coal is that the reactions take place over an extremely long period," said Hatcher, who is an associate professor of fuel science and geosciences at Penn State.

The correct answer is (a) wood → peat → lignite → bituminous coal To explain: The wood is converted into coal steps wise. It is in the order of wood →peat →lignite →bituminous coal. The bituminous coal is later converted into anthracite or graphite.

The process of transforming vegetable matter into coal usually occurs in two main steps: the biochemical and the physicochemical stage of coalification (Stach et al. 1982; Diessel 1992). In the biochemical stage, organisms initiate and assist in the chemical decomposition of vegetal matter, and in its conversion into peat and brown coal.

FischerTropsch plants associated with biomass or coal or related solid feedstocks (sources of carbon) must first convert the solid fuel into gases. These gases include CO, H 2, and alkanes. This conversion is called gasification. Synthesis gas ("syngas") is obtained from biomass/coal gasification is a mixture of hydrogen and carbon monoxide.

Introduction: Charcoal is made by heating wood or other organic materials above 400° C (750° F) in an oxygenstarved environment. The process, called pyrolysis, is exothermic meaning it gives off heat once started. The more volatile elements in the wood, such as hydrogen, oxygen, and some carbon, combine to form gasses that escape from ...

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).
