Torrefaction is a thermal conversion method of biomass used to produce a highquality solid biofuel that can be used for combustion, gasification, and additional nonenergyrelated applications. Torrefied biomass has numerous advantages above today's standard biomass fuels like log wood, wood chips, and white wood pellets (WWPs). This is known and promoted for long, and has been proven in ...

The fixed carbon content of the coal is the carbon found in the material which is left after volatile materials are driven off. This differs from the ultimate carbon content of the coal because some carbon is lost in hydrocarbons with the volatiles. Fixed carbon is used as an estimate of the amount of coke that will be yielded from a sample of ...
