Property of a Chinese Coal Treated by Thermal-Hydrogenation

Abstract

Morphological and its morphology change of inert maceral in a Chinese coal were studied during its thermal hydrogenation treatment around 673K under hydrogen pressure of 5MPa. Chemical digestion as well as physical agitation during the treatment are expected to reduce the size of inert component in the resultant additive according to the morphology of the inert maceral in the raw coal. The additive thus prepared was added to the coking of raw rank coal. It is also concerned how the inert maceral in the additive and feed coals behave during the coking.
