ABSTRACT:

In the third quarter work continued on the two major tasks: Task 2 - Development of Improved Supported Catalyst Compositions; and Task 3 - Slurry Reactor Kinetic Studies. Within Task 2, work was accomplished in studying the effect of catalyst activation procedure on activity and selectivity of the basecase Co sub 2 (CO) sub 8 j/Zr(OPr) sub 4 /Al sub 2 O sub 3 composition. Activation with pure H sub 2 gave a >100% increase in both bulk and specific activity in gas phase tests at 220 sup 0 C compared to the standard syngas activation. However, the activity enhancement was somewhat less at higher run temperatures. To establish a reference for the cobalt carbonyl-based catalysts, a catalyst was prepared and gas phase tested in which cobalt nitrate was used as the cobalt source and supported on zirconated alumina. Syngas and pure H sub 2 activation were also compared for this catalyst. A Co sub 2 (CO) sub 8 /Zr(OPr) sub 4 /Al sub 2 O sub 3 catalyst with increased cobalt loading was prepared to examine the effect of metal loading on catalyst performance. Initial analysis of these catalysts has been carried out using x-ray photoelectron spectroscopy (XPS) and H sub 2 chemisorption. Four catalysts were screened in the slurry phase reactors. These included the titanium promoted Co sub 2 (CO) sub 8 on alumina catalyst, the Co sub 2 (CO) sub 8 /Zr(OPr) sub 4 on alumina composition having a higher Co/Zr weight ratio of 1.15, and the potassium promoted mixed-metal composition of FeCo sub 3 (CO) sub 12 on alumina. The fourth slurry screening test was done to examine the effect of pure H sub 2 activation on the performance of the basecase Co sub 2 (CO) sub 8 /Zr(OPr) sub 4 on alumina catalyst. 63 figs., 131 tabs.
