Heavy oils derived from petroleum were separated by using the method developed by the USBM-API (5) Project 60 and analyzed by means of mass spectroscopy. The procedure used for separation and characterization of petroleum heavy oil was adopted to study heavy oil from coal liquids derived from Char-Oil-Energy-Development (COED) Syncrude from Utah coal (6) and western Kentucky coal (7) and Synthoil from West Virginia coal (i, 8). 

In the char-oil energy development (COED) process (Figure 19.3), crushed coal (0.125 in. [3 nun]) is dried and heated to successively higher temperatures in a series of reactors, which results in the incremental removal of volatile matter from the coal (Jones, 1973, 1975 McCray et al., 1979). The maximum temperature of each reactor has to be carefully controlled so that it r ains appreciably lower than the temperature at which the coal will cake (or agglomerate), thereby reducing the effectiveness of the individual fluidized beds. Thus, reactor temperatures and the number of reactors are dictated by the character of the coal feedstock in the final reactor, the product char is used to generate heat for the process.
