A detailed chemical study has been made on a suite of 27 Australian coals of varying rank. The coals had a wide range of H/C values and, in addition to chemical analysis, were examined by Fourier transform infrared spectroscopy and 13C solid state n.m.r. The coals were reacted with hydrogen in tetra

Asphaltene derived from brown coal was hydrogenated in the temperature range 375-450ยฐC with and without the addition of a sulphided nickel molybdate catalyst at initial hydrogen pressures from 2 to 10 MPa and the products were characterized by elemental analysis, non-aqueous titration for acidic oxy

## Letters to the Editor The contact angles of brown coals are plotted with their oxygen content in Figure 2, where a fair rectilinear relation is observed. The two kinds of coals can bc classified on the basis of their atomic ratio O/C. The higher value of O/C > 0.15 of brown coal may imply a hig

Catalyst deactivation in the repeated hydrotreatments of asphaltene in the liquid produced from an Australian brown coal was studied comparatively in single and two stage reactions, using commercial Ni-Mo/AI,O, catalyst in a batch autoclave. Although the H/C (atomic ratio) andf, (carbon aromaticity)
