Torrefaction removes moisture and volatiles from biomass, leaving biocoal. Torrefaction of biomass,, wood or grain, is a mild form of pyrolysis at temperatures typically between 200 and 320 °C. Torrefaction changes biomass properties to provide a better fuel quality for combustion and gasification applications. Torrefaction produces a relatively dry product, which reduces or eliminates ...

Coal is slightly denser than water ( megagram per cubic metre) and significantly less dense than most rock and mineral matter (, shale has a density of about megagrams per cubic metre and pyrite of megagrams per cubic metre). Density differences make it possible to improve the quality of a coal by removing most of the rock matter ...
