ABSTRACT:

The objective of the contract is to develop a catalyst and operating conditions for the direct conversion of syngas to liquid hydrocarbon fuels, using microporous crystals (''Molecular Sieves'') in combination with transition metals. During this past quarter, five catalyst test runs were completed. Four runs were devoted to exploring potential further applications of three selected additives which were among the constituents of some of the most effective catalysts developed to date. In particular, the object was to test whether these additives might enhance the effectiveness of the thorium promoted cobalt oxide class of catalysts. For the most part the three additives tested contributed little or nothing to the performance of catalysts using cobalt oxide intimately contacted with UCC-103, with or without promoters. A designed package was submitted to the MITRE Corporation for their economic evaluation of the cobalt Fischer-Tropsch catalysts used in conjunction with an isothermal tubular reactor operation at 270C and 300 psig, using a 2.3:1 recycle: feed gas recycle ratio, and giving an 85% overall syngas conversion for discreetly different levels of methane production.
