Hydrogen transferring liquefaction using hydrogenated fluoranthene at high temperatures was very effective for three Japanese bituminous coals, with a total yield of oil and asphaltene > 85 wt%. The high temperatureshort contact time conditions (480ยฐC for 10 min or 510ยฐC for 2.5 min) resulted in a t
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
