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 and 2 deal with the analyses and liquefaction experiments, respectively, whereas Task 3 deals with the economic impact of utilizing the pretreatment methods. This quarter we concentrated on Tasks 1 and 2, which are summarized below. This quarter we analyzed products derived from liquefaction experiments using the Fe(CO)₅ catalysts, under process conditions where carbon monoxide atmospheres and water contents were varied. During this quarter we compared coal conversions using Fe(CO)₅ with CO and CO/H₂ atmospheres and determined the product distributions. In particular, the effect of a 20% CO/H₂ atmosphere and 50% CO/H₂ atmosphere. These conversions were conducted with and without the presence of additional water. We found that the Fe(CO)₅ under a pure hydrogen atmosphere gave better conversions than under a CO/H₂ atmosphere in terms of THF solubility, but the addition of CO seemed to give good yields of oils with reduced oxygen contents. Interestingly when water was added to attempt to increase the effectiveness of the CO by utilizing the water-gas-shift reaction, less oils were observed. It is not obvious at the moment if this reduction is due to emulsions in the work-up or differences in chemical reactivities.
