PROPENSITY OF RAW VICTORIAN BROWN COAL FOR PHYSICAL ADSORPTION OF NITROGEN, OXYGEN, CARBON-DIOXIDE AND WATER

Abstract

A brief investigation of the relative propensity of untreated Victorian brown coal for physical adsorption of oxygen, nitrogen, carbon dioxide and water has been made. Due to the similarities between the physical properties of nitrogen and those of oxygen, nitrogen has been taken as a non-reacting oxygen model. The measurements show that physical and reversible adsorption of water occurs to a significant extent under the conditions usually applied in low temperature coal oxidation studies.
