It was shown previously that coal liquids from five major demonstration processes (Synthoil, HRI H-Coal, FMC-COED, PAMCO SRC, and Catalytic Inc. SRC) could be separated reproducibly, in high yields (94-99%) into five fractions by solvent fractionation (1,2). We now wish to report structural characterization parameters obtained for these materials by the use of proton nuclear magnetic resonance ( H NMR). 

The silylation results are presented in Table II. The results indicate that asphaltenes produced in SRC processes (PAMCO and Catalytic Inc.) contain practically all of their oxygen as phenolic oxygen. However, asphaltenes from catalyzed hydrogenation (Synthoil and HRI H-Coal) and staged pyrolysis (FMC-COED) contain only 51-61% of... 

The authors wish to thank the FMC Corporation, Hydrocarbon Research Inc., Catalytic Inc., PAMCO, and the Pittsburgh Energy Research Center of ERDA for generously supplying samples of their coal liquid products. The work described here was sponsored by the United States Energy Research and Development Administration under Contract No. E( 49-18) 2031. 

Reagents. Shale oil used in this study was obtained by retorting at 500°C the Green River Oil Shale from Anvil Point, Colorado. Petroleum Crude oil was obtained from Long Beach Field, California. Coal liquid was obtained from the PAMCO process.
