Use of asphaltene instead of the parent coal as the starting material for hydrogenolysis makes it easier to discuss the reaction mechanism, because the mean chemical structures of both reactant and products can be deduced from structural analysis. In this study asphaltene from Japanese Akabira coal

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
Coal-derived asphaltenes are complex aggregate organic materials. The high viscosity of asphaltenes has been attributed to organic (pyridine) base-organic (phenols) acid interaction. Reduction of asphaltene viscosity by selectively oxidizing with thallium(lll) salts was attempted. TI(III) treatment
Coal-derived asphaltenes from five majordemonstration processes in the United States (Synthoil, HRI H-Coal, FMC-COED, PAMCO SRC, and Catalytic Inc. SRC) have been separated by a simple, rapid chromatographic procedure, on silica gel, into a limited number of acid/neutral and basic fractions which co
