Mechanochemical activation of coal from the Erkovetskoe deposit and its reactivity in a liquefaction process

摘要

The results of experimental studies on an increase in the reactivity of brown coal from the Erkovetskoe deposit upon hydrogenation under a low pressure of hydrogen (10 MPa) by crushing in a vibrating mill and a universal disintegrator activator (UDA) are reported. The high efficiency of the application of UDA technology to coal preparation at the stage of crushing, catalyst supporting, and coal-oil paste preparation on coal liquefaction by hydrogenation is demonstrated.
