Аннотация: The effect of preliminary mechanical activation in the energy-intensive mill-activator on the structural and chemical transformations of brown coals and their reactivity in contact with solvents has been established. Mechanical treatment of the brown coals from Kansk-Achinsk Basin was performed in a high-energy AGO-2 centrifugal planetary ball mill. Mechanical activation led to a partial destruction of the supramolecular structure of coal, reduction of the crosslinking degree of nano-sized polyaromatic clusters in the organic matter coal. This results in the increased reactivity of coal in the liquefaction processes (extraction and hydrogenation) to form liquid products. © 2006-2015 Asian Research Publishing Network (ARPN).
