Coalification

The coalification of peat to brown coal transforms the degraded plant matter from a hydrosol (an aqueous dispersion containing about 10% solids) to a colloidal gel of about 30-40% solids. The water in brown coal is an integral component of the structure and its removal results in the irreversible loss of the gel structure, i.e. the formation of ...
