Chemical analysis and biological testing of catalytic-catalytic two-stage direct coal liquefaction process materials
The purpose of this paper is to highlight the results of the chemical analysis and biological testing of the pressure filter liquid (PFL) and product distillate brand (PDB) materials from the 25-day demonstration run of the CTSL process. Where applicable, the data from the analyses of the CTSL materials are compared to the results obtained from similar analyses of other two-stage coal liquefaction processes. The comparative processes include the integrated two-stage liquefaction (ITSL) and the nonintegrated two-stage liquefaction (NTSL) processes. Chemical analyses were performed on fractions isolated from the PFL and PDB materials by adsorption column chromatography. Chemical class fractions of aliphatic hydrocarbons (AH), polycyclic aromatic hydrocarbons (PAH), nitrogen-containing polycyclic aromatic compounds (NPAC), and hydroxy-substituted PAH (hydroxy-PAH) were produced using neutral alumina as an adsorbent. Due to the high concentration of hydrogenated and partially hydrogenated components present in these samples, the hydroaromatic compounds were isolated using picric-acid-coated alumina as an adsorbent. Selected chemical fractions isolated from the PFL and PDB materials were then analyzed by high-resolution gas chromatography, gas chromatography/mass spectrometry, and low-voltage probe-inlet mass spectrometry. The biological activity of the CTSL materials was measured using two bioassays. The mutagenic response of all crude samples and chemical class fractions was measured using the histidine reversion microbial mutagenicity test with Salmonella typhimurium, TA98. Selected crudes were tested for tumorigenic potential using the initiation/promotion assay for tumorigenicity in mouse skin. 11 refs., 10 figs.
