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.

Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chlorine and sodium.

Biomass contains stored chemical energy from the sun that is produced by plants through photosynthesis. Biomass can be burned directly for heat or converted to liquid and gaseous fuels through various processes. Biomass was the largest source of total annual energy consumption until the mid1800s.

In a study led by Barcelos and Sundstrom, the scientists used nontoxic chemicals, commercially available enzymes, and a specially engineered strain of yeast to convert wood into ethanol in a single reactor, or "pot." Furthermore, a subsequent technological and economic analysis helped the team identify the necessary improvements required to reach ethanol production at 3 per gasoline ...

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.

The formation of charcoal under laboratory conditions has been studied and the following stages in the conversion process have been recognised. at 20 to 110°C The wood absorbs heat as it is dried giving off its moisture as water vapour (steam). The temperature remains at or slighly above 100°C until the wood is bone dry. at 110 to 270°C

The production of methanol only from coal has an estimated efficiency of 41 to 55 percent; but if methane and coal liquids are produced simultaneously, the overall process efficiency can climb to 75 percent. Waste and wood can also be used as energy sources. Conversion from these sources to methanol is likely to be somewhat less efficient ...

Gasification: this is the process in which solid biomass fuels ( wood, charcoal) are broken down by the use of heat to produce a combustible gas, known as producer gas; Densification: to overcome the bulky nature, low thermal efficiency and smoke emission of wood and agriculture residues, these can be processed to produce smokeless briquettes.

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.

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 ...
