Hydrogen behaviour at coal liquefaction reaction

摘要

It is studied that hydrogen behaviour of gas phase and that of liquid phase at the various kinds of coal liquefaction conditions, and reaction mechanism is discussed. So it is considered that hydrogen transfer quantity of gas phase is owing to coal liquefaction conditions, but that of liquid phase depends on hydrogen donor ability of recycle solvent. And it is considered that donor hydrogen of liquid phase might be transferred effectively by compensating hydrogen under decreasing gas phase hydrogen quantity at coal liquefaction reaction.
