Carbon Monoxide Reduction of Iron Ore
C ERTAIN attention is paid today to the weaknesses of the classical blast furnace process, and interest is continuously increasing in methods for direct reduction without melting. Several different methods have been developed or suggested in the past, but so far only a few have been adopted for practical use. Another tendency in the iron industry of today is the change-over to concentrates, wit...
متن کاملAn Investigation of the Reactions of Carbon Dioxide, Carbon Monoxide, Methane, Hydrogen, and Water over Iron, Iron Carbides, and Iron Oxides
Future long-duration manned space flights will require regenerative life-support systems. The Bosch process is one of several alternative regenerative life-support systems presently being evaluated by the National Aeronautics and Space Administration. 2H2 + CO2 = 2H20 + C Prototype Bosch units to reduce metabolic CO2 to carbon have been constructed and operated successfully with large recycle r...
متن کاملKinetics of Reduction of Iron Oxides and Ores by Carbon
ITIHEORETICAL considerations and experimental findings point out that reduction of iron oxides and I ores by carbon proceed via the gas' phase, whenever the latter is present. The overall reaction is a coupling of the following two component reactions, viz., Gasification of carbon C(S) CO2 (g) = 2C0 (g) and Reduction of iron oxide mFe.0y(S) -fCO (g) = nFezOw [S) CO2 (g) ' Recent kinetic studies...
متن کاملSelective catalytic reduction of sulfur dioxide by carbon monoxide over iron oxide supported on activated carbon
The selective reduction of sulfur dioxide with carbon monoxide to elemental sulfur was studied over ACsupported transition-metal oxide catalysts. According to the study, Fe2O3 /AC was the most active catalyst among the 4 AC-supported catalysts tested. By using Fe2O3 /AC, the best catalyst, when the feed conditions were properly optimized (CO/SO2 molar ratio = 2:1; sulfidation temperature, 400 ◦...
متن کاملCarbon monoxide binding to iron porphyrins.
The carbon monoxide affinities of iron complexes of meso-tetra (alpha, alpha, alpha, alpha-o-pivalamidophenyl)porphyrin (the "picket fence" porphyrin) and of a "picket fence" porphyrin derivative with an appended axial base have been measured in solution and compared with the CO affinities of various hemoproteins. The model complexes bind CO with much greater affinity than normal hemoproteins; ...
