Torrefied biomass is superior to any nontreated biomass in the offgassing behavior and is not subject to rotting, molding, or decomposition. Once densified, torrefied biomass shares many of the characteristics of coal (Järvinen and Agar 2014). The torrefaction step represents an additional unit operation in the biomass processing chain.

What is coal where is it found? FutureCoal World Coal Association

Coal is a fossil fuel, formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. Types of coal.

Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

Coke production remains an important use of coal. Coke is produced by heating coal under controlled conditions in the absence of air. This drives off some of the volatile materials and concentrates the carbon content. Coke is then used as a highcarbon fuel for metal processing and other uses where an especially hotburning flame is needed.
