Metal boride catalysts for indirect liquefaction. Annual technical progress report, September 1, 1983-August 31, 1984
Eight cobalt boride catalysts were prepared by new techniques involving either (i) coaddition of cobalt nitrate and NaBH/sub 4/ solutions or (ii) exposure of cobalt catalysts to B/sub 2/H/sub 6//H/sub 2/ at 350/sup 0/C. Catalyst compositions were determined from chemical analysis and XRD while physical properties were obtained from H/sub 2/ and BET adsorption measurements. H/sub 2/ adsorption on these catalysts is activated. Specific CO hydrogenation activities and selectivities of unpromoted cobalt, sodium-promoted cobalt, cobalt boride, and sodium-promoted cobalt boride were also measured. Cobalt boride is about as active as cobalt, sodium-promoted cobalt is less active; sodium-promoted cobalt boride is more active. Cobalt boride produces lighter hydrocarbons than cobalt; sodium-promoted cobalt and cobalt boride produce somewhat heavier products. The latter catalyst has unusual selectivity for C/sub 5/-C/sub 12/ hydrocarbons; however this selectivity decreases with increasing reduction temperature. 26 references, 5 tables, 14 figures.
