Journal ArticleDOI
Analysis of XPS spectra of Fe2+ and Fe3+ ions in oxide materials
Toru Yamashita,Peter C. Hayes +1 more
TL;DR: In this paper, the peak positions and peak shape parameters of Fe 3p for Fe2+ and Fe3+ were derived from the XPS spectra of the standard samples of 2FeO·SiO2 and Fe2O3, respectively.
Journal ArticleDOI
Production of Very Pure Hydrogen with Simultaneous Capture of Carbon Dioxide using the Redox Reactions of Iron Oxides in Packed Beds
Christopher D. Bohn,Christoph R. Müller,J. P. E. Cleeton,Allan N. Hayhurst,John F. Davidson,Stuart A. Scott,J. S. Dennis +6 more
TL;DR: In this article, a chemical looping process was formulated to produce separate, pure streams of H2 and CO2 from syngas, using a packed bed of the various oxides of iron.
Journal ArticleDOI
Modeling and simulation of hydrogen injection into a blast furnace to reduce carbon dioxide emissions
TL;DR: In this article, the potential to reduce CO2 emissions from blast furnace processes by using hydrogen as an auxiliary reducing agent, which is generated renewably by water electrolysis, is examined.
Journal ArticleDOI
Mathematical modeling of the reaction in an iron ore pellet using a mixture of hydrogen, water vapor, carbon monoxide and carbon dioxide: an isothermal study
TL;DR: In this paper, a mathematical time-dependent and isothermal model based on the grain model has been developed to simulate the kinetic and thermal behaviors of a porous iron oxide pellet undergoing chemical reactions with a mixture of hydrogen, carbon monoxide, carbon dioxide and water vapor.

Development of Iron Oxide Carriers for Chemical Looping Combustion Using Sol−Gel
A. M. Kierzkowska,Christopher D. Bohn,Stuart A. Scott,J. P. E. Cleeton,John S. Dennis,Christoph R. Müller +5 more
TL;DR: In this paper, composite particles with different mass ratios of Fe2O3 and Al2O 3 were prepared using a sol−gel method and were examined for use in chemical looping combustion through repeated reduction and oxidation cycles in a packed bed reactor at 850 °C.
