Kinetics 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 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 کاملThe Irony of Iron – Biogenic Iron Oxides as an Iron Source to the Ocean
Primary productivity in at least a third of the sunlit open ocean is thought to be iron-limited. Primary sources of dissolved iron (dFe) to the ocean are hydrothermal venting, flux from the sediments along continental margins, and airborne dust. This article provides a general review of sources of hydrothermal and sedimentary iron to the ocean, and speculates upon the role that iron-cycling mic...
متن کاملHighly dispersed iron oxides on mesoporous carbon for selective oxidation of benzyl alcohol with molecular oxygen.
Highly dispersed iron oxide supported catalysts, prepared using HNO3-treated CMK-3 mesoporous carbons as supports, exhibit relatively high catalytic activity in selective oxidation of benzyl alcohol with oxygen.
متن کاملAdsorption of Arsenate by Nano Scaled Activated Carbon Modified by Iron and Manganese Oxides
The presence of arsenic in water supplies is a major problem for public health and still concerns large parts of population in Southeast Asia, Latin America and Europe. Removal of arsenic is usually accomplished either by coagulation with iron salts or by adsorption with iron oxides or activated alumina. However, these materials, although very efficient for arsenic, normally do not remove other...
