Comparison of hydrocarbon extracts from seven coals by capillary GC and GC/MS
The chloroform extraction of seven coals yielded extracts that gave unique capillary gas chromatography (GC) profiles. Several groups of hydrocarbon biological markers were detected in the coal extracts by mass spectrometry using selected ion scans. n-Alkanes, pristane, sesquiterpenes, several tricycle alkanes and pentacyclic triterpanes with molecular weights from 398 to 454 were detected. The coal extract profiles fell into four groups: (1) BB1, BB2 (Texas lignites) and MOC (Australian lignite); (2) B3 (North Dakota lignite) and WY01 (Wyoming, subbituminous); (3) ALB1 (Alberta, Canadian subbituminous), and (4) POW1 (Ohio, bituminous). Profiles were characteristic and reproducible for each coal. 2 figures, 4 tables.
