Petroleum resid/coal co-processing feeds and product streams: Chemical and toxicological analysis
1986
The purpose of this manuscript is to report the preliminary results of the chemical analysis and toxicological testing of feedstock and product samples from two different DOE-funded co-processing technologies, and to compare these results to those obtained from two-stage coal liquefaction materials. Co-processing samples were provided from (a) run 3 of the catalyzed, slurry, single-stage co-processing technology of UOP, Inc., during lined-out operations of plant 558 with a Lloydminster petroleum resid and Illinois No. 6 coal and (b) runs CTS-5 and -6 of the two-stage, close-coupled, Lummus Crest, Inc. (LCI), co-processing pilot plant during lined-out operations with an Arabian heavy petroleum resid and Pittsburgh seam coal. Selected feed and product stream samples were chemically characterized using the following techniques: chemical class fractionation by adsorption column chromatography, gas chromatography, gas chromatography/mass spectrometry, low-voltage probe-inlet mass spectrometry, field desorption (FD) mass spectrometry, and nuclear magnetic resonance (nmr) spectroscopy. The biological activities of selected crude co-processing samples and chemical class fractions were measured using the standard histidine reversion microbial mutagenicity assay and an initiation/promotion assay for tumorigenicity in mouse skin. In addition to feed and product stream comparison of the co-processing samples, the results of the analyses and testing of the co-processing productmore » streams were compared to results from similar analyses of two-stage direct coal liquefaction (TSL) products. 15 refs., 10 figs., 6 tabs.« less
