The Process of conversion of wood into coal by biochemical process is known as Carbonization. Coal burns cleaner than wood burning coal was easier because coal burned longer than wood. Carbonization is the term for the conversion of an organic substance into carbon or a carboncontaining residue through pyrolysis or destructive distillation. It ...

Between about 1500 and 1660 Britain's basic fuel supply, wood, began to fail, and after much readjustment over a prolonged crisis was replaced by coal. The reasons for this growing shortage of wood fuel are various. Consumption of fuel increased as population grew and industry burnt more, while the supply seems to have dwindled as woodland ...

The answer is a process called coalification. Coalification is the transformation of organic matter into coal under high pressure and temperature. It involves several stages, such as peat formation, lignite formation, bituminous coal formation, and anthracite formation. Each stage represents a different degree of coalification and a different ...

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.

For this reason, any process used to convert coal to alternative fuels must add hydrogen (either directly or in the form of water). Gasification refers to the conversion of coal to a mixture of gases, including carbon monoxide, hydrogen, methane, and other hydrocarbons, depending on the conditions involved. Gasification may be accomplished ...

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 ...

It will cost you anywhere between 100 and 1,500 to convert your wood stove to a multifuel or gas stove. The actual cost will depend on the type of stove you have, the type of fuel you want to use, and the cost of labor in your area. If you have a basic wood stove, you can probably convert it to a multifuel stove for around 100.

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.
