ABSTRACT:

In the fourteenth quarter work continued for two major tasks: (1) Slurry Catalyst Development, and (2) Proprietary Catalyst A Development. The proprietary catalyst A work is part of a contract modification, begun last quarter, to improve the activity and center the selectivity for diesel fuel products of this catalyst. The basis of this work stems from promising results during extended testing of this catalyst. Variation of catalyst pretreatment methods and promoter levels are intended. Slurry catalyst development - Parametric gas phase screening tests were concluded on a modified conventional catalyst and an optimum preparation and activation procedure chosen for diesel fuel selectivity. A short term (approx. = 21 day) slurry test of this catalyst exhibited appreciable activity, but poor selectivity for diesel fuel products. The selectivity varied strongly with CO/H sub 2 ratio, but even at CO/H sub 2 = 2.0, products were predominantly below C sub 10 . Catalyst A development - Three tests were conducted this quarter to determine the effects of varying the promoter levels of catalyst A. In summary, the basecase catalyst composition of this catalyst remained to be the most selective for diesel fuel. In activity level, a catalyst A' out-performed the activity of all catalysts tested to date. Surface analysis studies are underway to aid in understanding these effects and in so doing, optimizing the promoter levels for maximum activity and diesel fuel selectivity. Gas phase screening tests were conducted on catalyst A to determine the effects of activation and pretreatment procedures on activity and product selectivity. In general, no appreciable differences in bulk activity and only slight differences in hydrocarbon distribution were observed in the three tests conducted. (ERA citation 10:022477)
