Pressure and temperature effects on hydrogenation reactions were examined using coal-derived asphaltene at 390,420 and 45o"C, under 3 and 10 MPa of hydrogen partial pressure. Higher conversion was obtained at higher reaction temperatures. Benzene-insoluble material (BI) was formed at higher temperat
Two Polish subbituminous coals, containing 76% and 82% C, were hydrogenated in a batch stirred autoclave at 400,430 and 46O"C, under 20 MPa hydrogen pressure and at contact times of 20, 60,90 and 120min, in the presence of a coal-derived recycle oil. No external catalyst was used. The filtered react
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
