“…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.…”

“…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.…”

In Fe-based Fischer-Tropsch Synthesis (FTS), the Fe carbides form under the carburizing H 2 : CO reaction atmosphere providing the active phases for hydrocarbon synthesis. H 2 reduced Fe (À NaÀ S)/α-Al 2 O 3 catalyst materials, with and without NaÀ S promotion, were carburized under CO at 240-440°C to form Fe carbides. X-ray Powder Diffractometry (XRPD) with Rietveld Quantitative Phase Analysis (R-QPA) and Mössbauer Absorption Spectroscopy (MAS) were used to identity and quantify the formed Fe carbide phases. The Fe carbides formed in order of increasing temperature are ɛ-Fe 3 C, η-Fe 2 C, χ-Fe 5 C 2 and θ-Fe 3 C. θ-Fe 7 C 3 and a distorted χ-Fe 5 C 2 phase are formed at 25 bar CO (340°C) from a Fe oxide precursor. Fe carbide formation was unaffected by NaÀ S addition, but it did increase Fe oxidation (� 290°C) and preferred formation of χ-Fe 5 C 2 over θ-Fe 3 C phase (� 390°C). The results unify the often ambiguous Fe carbide identification and nomenclature and specify the role of NaÀ S in the carburization process.

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.…”

This survey was prepared by SERI staff and a number of consultants for t h e ~e p a r t m e n t of Energy under Contract EG-77-C-01-4042, Task 3322. ~o m p i l e d ' i n three volumes, the survey covers the technical background of biomass gasification, the present status of research and'development, and recommendations for future work. Volume I, Synopsis and Executive Summary, condenses the body of the report for the more casual reader. Volume 11, Principles of Gasification, discusses the properties of biomass relevant t o gasification and the specific kinetics and thermodynamics of biomass gasification reactions; it is intended far the researcher or engineer. Vo111me 111, Current Technology and Research, details the present status of biomass technology and includes specific recommendations for the future. This survey has been compiled by a number of SERI staff members and consultants under the direction of T. B. Reed. Although many authors contributed to the survey and a r e listed in the Table of Contents, many others had less formal input. W e would like t o thank them for their efforts.
