Studies of the Fischer-Tropsch Synthesis. XIV. Hägg Iron Carbide as Catalysts1

“…Preparation of Hágg Carbide.-Fused catalysts were reduced in hydrogen (space velocity® about 2,500 hr.-1) at The reduction and carburization conditions used in the pretreatment of fused catalysts are given in Table II. Synthesis Tests and Analytical Methods.-The catalyst testing apparatus and methods have been described previously.8•18' 17,81 The pretreated catalysts were transferred in carbon dioxide to the synthesis reactor.…”

Fischer-Tropsch Synthesis. Nitrides and Carbonitrides of Iron as Catalysts

“…There is apparently a critical carbonnitrogen ratio which, when exceeded, causes decomposition of e-carbonitride to -iron carbide. In this transformation the nitrogen from the e-iron carbonitride (1) may go into the -phase, which then would really be -iron car-bonitride, (2) it may go into a phase of such small crystallite diameter that the diffraction pattern is too diffuse tó be detected, or (3) it may be eliminated as gas. This critical ratio varies from about 2 to 1 at 450°G.…”

Investigations of reactions along the catalyst bed in flow systems by vapour-phase chromatography. Part 1. The decomposition of methanol on a cobalt Fischer-Tropsch catalyst

“…The activation energy for the decomposition of methanol is of the same order as that for the decomposition of higher alcohols 10 and for synthesis. 16 The breakdown of methanol may proceed differently over an iron catalyst, as would seem indicated by the conclusions of Kummer and Emmett 8 that the methanol complex is directly involved in synthesis, since the amount of radioactivity observed in the hydrocarbons produced increases by 70 counts/min cm3 for each additional carbon atom, while the mean radioactivity for carbon monoxide is only 32 counts/min cm3. However, this argu'ment assumes that the radioactivity distribution in carbon monoxide is uniform.…”
