Many studies of the pyrolitic degradation of coal-derived and petroleum-derived aviation fuels have demonstrated that coal-derived aviation fuels are more stable than petroleum-derived aviation fuels. Refined chemical oil, which is a distillate from the refining of coal tar, is of special interest as it is blended with LCO coming from catalytic cracking of petroleum. Upon hydroprocessing, it is converted to tetralin and decalin compounds that are used to formulate a thermally stable jet fuel. Coal extraction using LCO as a solvent was carried out. At 350°C, the extraction and extract yields ranged from 14-39 and 10-32 wt %, respectively. Between the factors studied, temperature and LCO/coal ratio have the most important effect on the extraction process. This is an abstract of a paper presented at the 228th ACS National Meeting (Philadelphia, PA, 8/22-26/2004).
