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
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
