direct reduced reactions

: Direct Reduction Process - an overview ScienceDirect

The direct reduction processes in combination with the melting of directly reduced iron to produce steel in the EAF offer an alternative to the BF-BOF route. The basis of the direct reduction process is that solid sponge iron is produced by removing oxygen from the ore in a shaft furnace, rotary kiln furnace or fluidised bed. Sponge iron can be produced in the form of Direct Reduced Iron (DRI), Hot Briquetted

2013-6-25 (The reactions in which oxidation and reduction takes place in the same vessel (or solution) are called direct redox reactions). Example: zinc rod is dipped in copper sulphate solution. The redox reaction takes place and during the reaction, zinc is oxidised to zinc ions and copper ions are reduced to metallic copper due to direct transfer of ...

: Oxidation-Reduction Reactions Boundless Chemistry

Redox reactions are matched sets: if one species is oxidized in a reaction, another must be reduced. Keep this in mind as we look at the five main types of redox reactions: combination, decomposition, displacement, combustion, and disproportion. Combination. Combination reactions “combine” elements to form a chemical compound.

2012-1-5 4.4 Direct Reduction. Direct reduced iron is iron ore in the form of lumps, fines or pellets that have had the oxygen removed by using hydrogen and carbon monoxide. Typical sources of carbon monoxide are natural gas, coal gas, and coal. Other energy inputs into the production process often include oil and electricity.

2021-3-22 Reactions which do involve gain or loss of one or more oxygen atoms are usually referred to as 'oxygenase' and 'reductase' reactions, and are the subject of section 16.10 and section 17.3. For the most part, when talking about redox reactions in organic chemistry we are dealing with a small set of very recognizable functional group transformations.

: Direct Nuclear Reactions - World Scientific

The difference between direct and compound nuclear reactions has been discussed. In the direct reaction, the incident particle interacts with the target nucleus only several times at most. Therefore the change produced in the target must be a simple rearrangement of one or several nucleons or collective degrees of freedom.
