Research under way in this project centers upon developing and evaluation catalysts and process improvements for coal liquefaction in the two-stage close-coupled catalytic process. The project is being carried out under contract to the United States Department of Energy. As discussed in the previous quarterly report, the results showed that C/T liquefaction is not a good option for Black Thunder subbituminous coal. In this quarter, the liquefaction of Black Thunder coal was continued. The studies showed that the combination of Wender`s sulfated iron oxide with molybdenum is the most effective catalyst for this liquefaction. Compared with other iron/molybdenum catalysts, distillate yields were increased and the catalyst deactivation was not as severe as for the supported (extruded) catalysts. |
