ABSTRACT:

Results produced during the year ending February, 1982, are presented. The objective of the contract is to develop a catalyst and to select operating conditions for the direct conversion of syngas to liquid hydrocarbon fuels, using microporous crystals - molecular sieves - in combination with transition metals. In Task 1, shape-selective catalysts (SSC's) will be evaluated for converting low molecular weight liquids (e.g. methanol and small olefins) to desired products such as gasoline, turbine and diesel fuel. In Task 2, the feed will be syngas (CO + H sub 2 ), and the catalyst will be a combination of transition metal component (MC) and SSC. Task 3 is a study of surface effects and reaction intermediates during the hydrogenation of carbon monoxide. A number of catalysts of different structure have been prepared at various levels of acidity to aid in selection of the SSC component. During the first year of the program, equipment was assembled to enable fairly rapid testing of candidate catalysts at a variety of conditions. Fairly complete data are available from two runs made during the second and third quarters of the contract, using a UCC Berty reactor. The first run used methanol feed over a high silica zeolite catalyst, and resulted in making products in the gasoline boiling range. The second preliminary run used iron as the Fischer-Tropsch active component, supported on a relatively inert amorphous silica-alumina base. This was a Task 2 run, with syngas as the feed. Although the fraction of feed connected to hydrocarbons was rather low, the fraction of that which was undesired solid was much less than with methanol feed. (ERA citation 08:011962)
