ABSTRACT:

Commercial Fischer-Tropsch (F-T) processes are limited by deficiencies intrinsic to the metal catalysts used (Fe and Co). These are (1) the predominance of normal paraffins in the product, (2) a small liquid motor fuel fraction formed in the total product, and (3) the formation of oxygenated compounds which cause separation and corrosion problems. Research was undertaken to identify molecular sieve candidates that showed improved F-T performance in conjunction with conventional F-T catalyst base metals (Fe and Co). That work identified a few outstanding candidates that provided significantly better yields and product quality and, in addition, exhibited improved catalyst stability when compared with currently available commercial catalysts. This program was initiated to capitalize upon the leads generated by the previous work. The objective included a demonstration of the economic value of a combined catalyst process system. 23 figs., 14 tabs.
