The Hazards to Health in the Hydrogenation of Coal

Analysis of hydroaromatics in coal-derived synthetic fuels: applications to pilot-plant samples

“…Numerous studies have been undertaken in the past to identify the heterocyclic compounds in coal-derived products, the most successful utilizing capillary column gas chromatography and gas chromatography/ mass spectrometry (GC/MS) (1, 2). Considerable information is presently available with respect to speciation of nitrogen-containing (1)(2)(3)(4), sulfur-containing (5,6), and oxygen-containing (7,8) PAC as a result of these studies. In most cases, compounds containing only one heteroatom were considered.…”

Health and environmental effects document for direct coal liquefaction - 1981.

“…This may be due to increased attention to worker hygiene or to insufficient time for most organ cancers to develop because of their long latency period. In a coal hydrogenation plant at Institute, West Virginia, Sexton (1960) reported cutaneous cancers and precancerous lesions in workers exposed to coal liquefaction products. In a recent follow-up mortality study of the workers with skin cancer and precancerous lesions, no cancer deaths were observed (Palmer 1974).…”

Separation of hydroaromatic compounds in synfuels by picric acid columns

“…1964, 43, 374-385. of synthetic liquid fuels from coal. The increased aromatic and heteroatomic content of these synthetic fuels, as compared to petroleum, has raised some concern about their toxicity and mutagenicity (1)(2)(3). Identification and elimination of specific mutagenic compounds have led to process changes which reduce the levels of primary aromatic amines (PAA) and polycyclic aromatic hydrocarbons (PAH) (4,5).…”
