ABSTRACT:

Initial Task 1 tests used methanol as the feed. It was found that catalysts of interest tended to make highly methylated aromatics in the Berty reactor. Although a simulated distillation showed that these products boiled in the gasoline and diesel range, most were solid at room temperature. Aromatic products frequently are desirable constituents of gasoline, but highly methylated aromatics which precipitate at the concentrations found are undesirable. Since small olefins are products and intermediates in reactions over Fischer-Tropsch catalysts, propylene was chosen as feedstock to replace methanol. Catalysts for syngas feed (task 2) have a metal component (MC) and a shape-selective component (SSC). Four techniques have been used in synthesizing our bi-functional catalysts. The data presented show that catalysts and conditions have been found which enable converting 1:1 H sub 2 /CO syngas feed at reasonable conversions in one step to motor fuel range products with quite acceptable selectivity to C sub 5+ products. Two effects should be noted. The molecular sieves used reduced the high boiling (wax) component of the product as compared to physical mixture with the relatively inert alpha -alumina. Also the quality of the gasoline range product with the molecular sieve is much better than with the F-T type catalyst. (ERA citation 09:039813)
