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.

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 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 ...

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 ...

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.

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.

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.
