Metal boride catalysts for indirect liquefaction. Quarterly technical progress report, September 1-November 30, 1983
During the fifth quarter six boron-promoted cobalt and iron catalysts were prepared by new procedures developed in this laboratory. The cobalt preparations produced high surface area cobalt borides; the iron preparations were unsuccessful. The cobalt boride catalysts were characterized by chemical analysis, BET, and H/sub 2/ chemisorption. Two unsupported catalysts reduced at 250 and 350/sup 0/C respectively were tested for CO hydrogenation activity and selectivity at 1 atm. The results confirm that boron-promoted cobalt is particularly selective for C/sub 5/-C/sub 12/ hydrocarbons and for C/sub 3/-C/sub 7/ olefins. Methane and C/sub 2/-C/sub 4/ makes increase while C/sub 5/-C/sub 13/ make decreases with increasing reduction temperature. Our liquid nitrogen Moessbauer cell was redesigned and refitted for high vacuum operation. It will be used to test iron borides at liquid nitrogen temperatures since most of the room temperature data were not definitive.
