Summary
The objectives of this project are to study the effect of pretreatment methods on the two-stage liquefaction process. In particular, the effects of dispersed catalysts and carbon monoxide atmospheres on a coal liquefaction process. The project is divided into three technical tasks. Task 1 involves the analyses of the liquefaction products derived from liquefaction experiments using the catalysts Fe(CO)₅ and the sulfated iron catalyst, Fe₂O₃·SO₄. We also analyzed the products derived from treating the recycle vehicle under coal liquefaction conditions with no coal or catalyst present, and found that the toluene and THF fractions had low H/C ratios. No CO or CO₂ gases were detected after reaction, although considerable amount of methane gas was produced, suggesting that during the liquefaction runs the carbon oxides are produced only from the coal, as expected, but that methane gas is produced both from the recycle solvent and the coal. We now have more information about the recycle solvent from Wilsonville, who report that the residue was 63%, composed of 45% resid and 18% insoluble inorganic (CI), and a distilable portion of 37% (1050°F). During this quarter we compared coal conversions using Fe(CO)₅ with CO and H₂/CO atmospheres and determined the effect of using sulfated iron (Fe₂O₃·SO₄) as a conversion catalyst. Also, the coal liquefaction recycle vehicle was subjected to coal product distribution. We found that the Fe(CO)₅ under a pure hydrogen atmosphere gave better conversions than under a CO/H₂ atmosphere in terms of oils and asphaltenes but was equal in terms of overall conversion into soluble fractions.
