Reduction Kinetics of Natural Ilmenite Ore with Carbon Monoxide

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...

KINETICS OF CARBOTHERMIC REDUCTION OF AN IRANIAN CELESTITE ORE

Two commercial methods are used for the production of strontium carbonate:1) Direct conversion of Celsetite to strontium carbonate by hot sodium carbonate,2) Carbothermic reduction of celestite with coal followed by water leaching of strontium sulfide(SrS) and its conversion to strontium carbonate.The present study has been made on the carbothermic reduction of celestite ores of Varamin (Iran) ...

Ignition Kinetics of Carbon Monoxide - Oxygen Reaction

The Deoxygenation Kinetics of Hemoglobin Partially Saturated with Carbon Monoxide

The deoxygenation rate of hemoglobin solutions partially saturated with carbon monoxide, in the presence and absence of 2,3-diphosphoglycerate (2,3-DPG) at 23” and pH 7.0 and 8.0 have been measured. When the rate is calculated over the initial, 30% of the reaction, solutions containing 98% HbOa show an increase in the rate as hemoglobin deoxygenates both at neutral and alkaline pH. Partial satu...

Copper Deoxidation Kinetics Utilizing Carbon Monoxide

Gaseous deoxidat ion of l iquid copper with carbon monoxide as the r educ ing gas has been examined . The r educ ing gas was in t roduced at a s u b m e r g e d or i f ice so that well c h a r a c te r ized , s ingle bubbles were formed. The deoxidat ion k ine t ics a r e d e t e r m i n e d p r i m a r i l y by the m a s s t r a n s p o r t of oxygen in l iquid copper. No effect of su l fur ov...
