Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.
What is Coke give its uses?
The most common use of coke is as a fuel for stoves, furnaces and blacksmithing. It is sometimes preferred over coal because burning coke produces very little smoke. It is also used to produce iron in a blast furnace. Coke is used to manufacture steel and many other materials.
What are the uses of coke Class 8?
The uses of coke are as follows: It was used for domestic heating in the past. It is used for the extraction of metals. It is used in the manufacture of steel.
The characteristics of coke are as follows:
- It is a tough, porous and black substance.
- It is an almost pure form of carbon.
- It gives little or no smoke.
What is Coke Chemical?
The residue is chiefly carbon, with minor amounts of hydrogen, nitrogen, sulfur, and oxygen. Also present in coke is the mineral matter in the original coal, chemically altered and decomposed during the coking process. coke. Coke.
What is difference between coal and coke?
What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.
Why Coke is not used as a fuel?
The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.
What is hard coke?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. … The carbon monoxide produced by its combustion reduces iron oxide (hematite) in the production of the iron product.
What are characteristics of coke?
Characteristics of Coke:
- It is an almost pure form of carbon.
- It is a tough, black and porous substance.
- It is made by heating coal in the absence of air.
- It burns without producing any smoke.
Which fuel is known as black gold?
How is coal formed?
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Is pet coke harmful?
First, the MDEQ most certainly did find that there are health threats from petroleum coke, stating that “Human exposure to fine particulate matter (PM) emissions from petcoke storage piles, at sufficiently high concentrations and durations of exposure, could cause respiratory and cardiovascular effects characteristic …
What materials are used in Coca Cola?
- Carbonated water.
- Sugar (sucrose or high-fructose corn syrup (HFCS) depending on country of origin)
- Phosphoric acid.
- Caramel color (E150d)
- Natural flavorings.
What is green coke used for?
Green coke with this low metal content is called anode-grade coke. When green coke has excessive metal content, it is not calcined and is used as fuel-grade coke in furnaces.
What is Coke in coal?
By distilling bituminous coal in retorts to obtain gas for illumination, or by burning it in kilns or pits, the residue left behind is called coke, which is simply coal charcoal, and is nearly pure carbon.
Is Coke a clean fuel?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.
Which is better coke or coal?
Coke is a better fuel than coal because; -Coke produces more heat on burning than coal. -Coke has a higher calorific value than coal. When equal masses of coke and coal are burnt, coke produces more heat.
