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

FeN nanoparticles confined in carbon nanotubes for CO hydrogenation

“…3 reveal that Fe x N catalysts do not exhibit obvious oxide phase after reaction. Substantially retarded oxidation in nitrided iron catalyst was also reported by Shultz et al 25 Therefore, the much lower activity of Fe-in could be attributed to the instability of iron and iron carbide under CO hydrogenation conditions.…”

Identification of Iron Carbides in Fe(−Na−S)/α‐Al2O3 Fischer‐Tropsch Synthesis Catalysts with X‐ray Powder Diffractometry and Mössbauer Absorption Spectroscopy

“…As a final remark, it is important to note that the behavior, crystal structures and X-ray diffraction patterns of the ɛ-Fe 3 C and η-Fe 2 C phases are very similar to their close, yet more stable, cousins of ɛ-Fe 3 N and ζ-Fe 2 N Fe nitrides. [104][105][106][107][108][109][110] A comparative study of the ɛ-Fe 3 C and η-Fe 2 C crystal structures in contrast to the structures of ɛ-Fe 3 N and ζ-Fe 2 N phases, phase properties and FTS behavior would be a good topic for future research.…”

Survey of Biomass Gasification, Volume III: Current Technology and Research

“…The production of aldehydes via the hydroformylation of olefins had been accomplished on the laboratory scale in the early portion of this century. Reviews of the application . 1957;Gates et al 1979) attribute t o Otto Roelen of Ruhrchemie AG in Germany the discovery of catalyst composition and reaction conditions a t which the reaction of the following type could occur.…”

“…13-6, this is achieved only a t the expense of a modest increase in the yield of methane. Approximately 50 to 60% of the synthesis gas is converted to liquid products (Shultz et al 1957).…”
