754. ------. [FRIEDMAN, A. H., AND MORAN, J. N.] (Phillips Petroleum Co.). Feldspar-Iron-Alkali Fischer-Tropsch Catalyst and Its Preparation. United States Patent 2,488,530, Nov. 22, 1949; appl. filed Feb. 10 1947. Serial No. 727,726; 11 claims (Cl. 252-459). Chem. Abs., vol. 44, 1950, p. 1672.

Fe oxide is fused with a mixed silicate of Al and an alkali or alkaline earth metal. The fused mixture is ground and reduced, usually with H₂, to convert the Fe oxide substantially to elemental Fe. The bulk density of the Fe catalyst is 1.8 or lower. Example; Fe wire burned in O₂ was mixed with equal weight of feldspar and fused in an oxyhydrogen flame. It was ground to 65- to 100-mesh. The bulk density was 1.8. After reduction 60 cc. of catalyst was reacted with synthesis gas H₂:CO=2:1 at 150 p.s.i. and 320º C., using 2,500 vol. of synthesis gas per vol. catalyst per hr. The yield was 6 cc. liquid product per hr., substantially all in gasoline range. After 54 hr. there was no wax on the catalyst and no C formation. A similar experiment using Fe wire without the feldspar yielded 4.5 cc. liquid product per hr. with some C and wax formation. 4 United States patents cited.
