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. … A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil refineries.
How is coke obtained from coal state three important uses of coke?
Coke is formed by the destructive distillation of coal. … 1) Coke is used as a domestic fuel. 2) Coke is used as a reducing agent in metallurgical processes. 3) Coke is used for producing fuel gases.
What are the important uses of coke?
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.
How is coke used to make steel?
Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel.
What is the difference between coke and coal?
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.
Is CNG obtained from coal?
Compressed natural gas is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). … CNG is made by compressing natural gas, which is mainly composed of methane (CH4), to less than 1% of the volume it occupies at standard atmospheric pressure.
Where is Coke used?
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.
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 is foundry coke?
Foundry coke is a high-quality grade of coke, also known as hard coal. … It is a large, strong coke used as a supporting matrix and energy carrier during foundry cupolas to produce cast and ductile iron products.
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.
How is coal made out of steel?
The most commonly applied process for steel-making is the integrated steel-making process via the Blast Furnace – Basic Oxygen Furnace. … Around 0.6 tonnes (600 kg) of coke produces 1 tonne (1000 kg) of steel, which means that around 770 kg of coal are used to produce 1 tonne of steel through this production route.
What is Coke made of?
Carbonated water – Approximately 90% of Coca‑Cola is water. The carbonated part is purified carbon dioxide, which gives the drink its “bubbles” or “fizz”. Sugar – Coca‑Cola Classic’s sweet taste (and also some of its mouthfeel) comes from sugar. Coca‑Cola Zero Sugar and Diet Coke are sugar free.
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.
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 …
