ABSTRACT:

The objective of this program is to develop a synthesis gas conversion catalyst with higher selectivity to liquid fuels, while maintaining catalytic activity and stability at least equivalent relative to state-of-the-art precipitated iron catalysts. Hydrocarbon cutoff hypothesis and developmental needs for a ruthenium catalyst with low light ends selectivity were investigated during this quarter. Hydrocarbon product distribution was Anderson-Schulz-Flory up to a carbon number of 250 and cutoff did not occur with a titania-supported catalyst containing ruthenium particles smaller than 20(Angstrom). It was found that an alumina-supported catalyst with 1% (by weight) ruthenium in the form of 50(Angstrom) to 100(Angstrom) metal particles was initially about half as active (by catalyst volume) and made one quarter of the amount of C(sub 1)(minus)C(sub 4) light end products relative to the Sasol precipitated iron catalyst.
