Paper Title:
Role of Hydrogen for Quick Coal Liquefaction at High Temperature
  Abstract

In this paper, the role of hydrogen for quick coal liquefaction at high temperament (QCLHT) was investigated by liquefaction of Yanzhou coal using a 17ml tubular resonance agitation miniature batch reactor. The result shows (1) that QCLHT of Yanzhou coal without catalyst using mixed solvents with different mole ratio of 1,2,3,4-tetrahydronaphthalene to naphthalene shows that hydrogen hardly participate the reaction and active hydrogen mainly comes from hydrogen donor solvents and hydrogen-rich belonged to coal itself (2) For QCLHT,. high-dispersed iron-based catalyst (and cocatalyst sulfur) not only promotes the activation of dissolved hydrogen but also accelerates the pyrolysis of coal, which results in the increase of liquefaction total conversion and light component.
