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 کاملEffects of Temperature and Particle Size Distribution on Barite Reduction by Carbon monoxide Gas
In this research, a mineral barite powder was reduced by carbon monoxide gas and the effects of reduction time and temperature was investigated as well as barite particle size. Results showed that the best result would be feasible when the barite particle sizes are between (-70 +100) in mesh scale. The barite reduction could reach the maximum level (98%) after reduction by carbon monoxide at 85...
متن کاملCatalytic reduction of nitric oxide by carbon monoxide.
The reduction of nitric oxide by carbon monoxide, reaction (l), mediated by metal complexes has attracted great attention recently due to its relevance to the control of air pollution and the intrinsic interest in the mechanism of N20 and C02 formation. 1-7 While a number of catalyst systems for reaction (1) have been reported, only the RhIILRhI and the PdC12CuCI2. systems rapidly catalyse the ...
متن کاملThermodynamics of carbon monoxide adsorption on polycrystalline titania studied by static adsorption microcalorimetry.
The adsorption of CO on polycrystalline TiO2 was investigated by static adsorption microcalorimetry. The initial differential heat of adsorption (qdiff,0) of CO on polycrystalline titania is 40 kJ/mol, and the standard adsorption entropy (Deltas0) is -104 J mol(-1) K(-1). These results are consistent with those derived from temperature-programmed desorption and FTIR results in the literature. T...
متن کامل2,4,6-trinitrotoluene reduction by carbon monoxide dehydrogenase from Clostridium thermoaceticum.
Purified CO dehydrogenase (CODH) from Clostridium thermoaceticum catalyzed the transformation of 2,4,6-trinitrotoluene (TNT). The intermediates and reduced products of TNT transformation were separated and appear to be identical to the compounds formed by C. acetobutylicum, namely, 2-hydroxylamino-4,6-dinitrotoluene (2HA46DNT), 4-hydroxylamino-2,6-dinitrotoluene (4HA26DNT), 2, 4-dihydroxylamino...
