Liquefaction reactivities for a suite of 4 coals from the Argonne Premium Coal collection have been measured in tubing bomb batch reactors. The coals span a rank range from low volatile through medium and high volatile bituminous to subbituminous. The coals were liquefied in 4 different vehicles (solvents) namely naphthalene, phenanthrene, tetralin, and 1-methylnaphthalene at 698 K (425 C), 6.2 MPa (900 psi) initial hydrogen pressure, and at 5 and 40 minutes residence times. The rate and extent of conversion to THF- and toluene-solubles was measured, and gas make and hydrogen consumption quantified directly. The data show that, for purposes of reactivity comparisons, conversion to toluene-solubles provides the most appropriate data for relative reactivity ranking purposes. The Wyodak subbituminous coal was found to have the highest rate of reaction of the four coals investigated, while the Illinois 6 high volatile bituminous coal exhibited the greatest extent of reaction (conversion to THF- and toluene-solubles).
