ABSTRACT:

This report describes work on Catalyst and Reactor Development for a Liquid Phase Fischer-Tropsch Process. The program contains four major tasks: (1) Project Work Plan, (2) Slurry Catalyst Development, (3) Slurry Reactor Design Studies, and (4) Pilot Facility Design. Two modified conventional catalysts were screened in the gas phase, and the improved results gave directions for further development work. Three slurry tests were run. The first, a 15 wt % slurry of a coprecipitated catalyst, showed non-standard Schulz-Flory product distributions, with a significant increase in C sub 9 + hydrocarbons. The second, a 19 wt % slurry of a support catalyst, also showed large deviations from the standard Schulz-Flory product, with a high selectivity for C sub 10 -C sub 25 hydrocarbons. Compared to a previous gas phase test, however, CH sub 4 yields were higher and the activity lower. A third slurry test of a supported cluster catalyst also showed a lower activity than in the gas phase. Oil analysis indicates that the reduction of activity observed for supported metal catalysts in the slurry compared to the gas phase may be due to poisoning by an oil component. An alternative oil will therefore be utilized for future tests. Seven supported cluster catalysts were synthesized and six were screened in the gas phase. In two cases, an increased yield of C sub 10 + products was observed, dependent upon the reaction conditions. Another showed a product selectivity that could be shifted between oxygenates and hydrocarbons. Gas hold-up and solids dispersion measurements in the 5'' column were completed for the 0 to 5 mu m and 45 to 53 mu m iron oxide/isoparaffin, and the 45 to 53 mu m and 90 to 115 mu m silica/isoparaffin systems. The gas hold-up results were correlated by statistical analysis. (ERA citation 07:046094)
