In blast furnaces
carbon monoxide
is the main reducing agent whereas carbon is a minor reducing agent.
Which is the effective reducing agent in the extraction of iron from haematite?
The effective reducing agent in the extraction of haematite is
carbon monoxide, CO
.
Which of the following oxidised is reduced in blast furnace?
Oxide of iron
is reduced in blast furnace.
In blast furnace, the reduction of ferric oxide by carbon mono oxide takes place.
Which one is used as reducing agent for fe2o3 in blast furnace?
Answer:
Carbon monoxide or CO
is the better reducing agent for hematite ore of iron in blast furnace.
Which element is reduced in blast furnace?
The blast furnace
Reactions in which
oxygen
is removed are called reduction reactions. In this reaction, the iron(III) oxide is reduced to iron, and the carbon is oxidised to carbon dioxide.
What is the purpose of hematite in a blast furnace?
Note: Blast furnaces are
to extract iron from iron ores
. Hematite is one of the irons which has 70% iron in it. In furnaces carbon monoxide is used as a reducing agent to extract iron from iron ores.
Which is used to reduce pure hematite to iron?
Natural hematite, the most widely studied Fe oxide, can be reduced by
hydrogen (H2)
[108], carbon monoxide (CO) [109, 110], and gas mixtures [111].
What is an example of a reducing agent?
A reducing agent typically is in one of its lower possible oxidation states and is known as the electron donor. Examples of reducing agents include the
earth metals, formic acid, oxalic acid, and sulfite compounds
. … The glucose (C
6
H
12
O
6
) is being oxidized, so it is the reducing agent.
What three metals are melted in blast furnace?
Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel, and they are also employed in processing
lead, copper, and other metals
.
Which substance is not involved in the extraction of iron from hematite?
Which substance is not involved in the extraction of iron from hematite? Which statement is incorrect?
Carbon dioxide
is a waste product in the extraction of iron. Carbon monoxide is a reducing agent.
Can Fe2O3 be reduced by Coke?
Figure 2: Ellingham diagram for the reduction of haematite.
Thus,
above 1073 K, carbon (coke) can reduce Fe2O3
, i.e., ∆rGo for the reaction, is negative (T greater than 1073 K.
Why is carbon used as most common reducing agent?
Carbon is a good reducing agent, especially at higher temperatures, because
it is a non-metal and it combines with oxygen and forms its gaseous non-metallic oxides
. Its dioxide CO2 being a gas, escapes away, hence it’s a good by-product as we don’t have to separate it further.
What are the limitations of Ellingham diagram?
Limitations of Ellingham Diagram
It ignores the reaction kinetics means it does not provide any information about kinetics of the reduction reaction
. The analysis is thermodynamic in nature, it means the reactions which are predicted by the Ellingham diagram can be very slow.
Why it is called blast furnace?
The Blast Furnace is a large steel structure about 30 metres high. … The furnace gets its name
from the method that is used to heat it
. Pre-heated air at about 1000
o
C is blasted into the furnace through nozzles near its base. The largest Blast Furnaces in the UK produce around 60 000 tonnes of iron per week.
What is the hottest furnace on earth?
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at
Furnace Creek Ranch
, in Death Valley in the United States.
Which fuel is best suitable for blast furnace process?
Which fuel is best suitable for blast furnace process? Explanation:
Coke
is best suitable for blast furnace process as it also acts as a reducing agent in smelting iron ore.
