The mechanism of a process for removal of water as liquid from soft brown coals has been investigated. Coals were heated in water under pressure to temperatures of 150 to 300ยฐC, and the yields of dry coal, water, organic functional groups and inorganics in the product were measured. The earlier conc

The vacuum desorption of water from brown coal has been investigated at temperatures from 30ยฐC to 120ยฐC. The amount of water which can be desorbed after prolonged evacuation to a constant weight increases with increasing temperature, and is accompanied by the evolution of carbon dioxide at temperatu
