Abstract

Comparative studies of the efficiency of ozone absorption by different coal samples in the course of their treatment with low ozone concentrations (250 mg/m³) at room temperature were carried out. It was found that the reactivity of coals toward ozone can be characterized in terms of the quantity of reacted ozone before reaching a specified degree of its conversion. The proposed procedure allows one to range coals based on their activity towards ozone at standardization of test conditions.
