The purpose of this work was to determine the effects of surface area variations of iron sulphides on coal liquefaction. Several iron sulphides were synthesized including pyrites (Fe!&) with 46.6 wt% Fe, pyrrhotites (Fe,.,S) with -60 wt% Fe and irortsulphur compounds of unknown composition. Surface

A preliminary study was undertaken to evaluate the effects of mixed solvents and added H,S on the overall conversions of a moderately reactive coal (Wyodak-2) as defined by tetrahydrofuran solubility. Conversion efficiencies were measured as a function of time and of H,S concentration in the H,S-tet
