Coke, often made from bituminous coal refuse, is formed from burning off volatile components. That leaves solid fuel that burns longer and hotter than coal.
Anthracite (hard) coal burns the hottest and cleanest, but this coal is in shorter supply because it takes longest to form.
Bituminous (soft) coal has variable amounts of volatile components (low, medium, high) and burns 'dirty'. But it provides long, fairly even burning.
Factories could and did use bituminous coal. But burning coal refuse to make coal rescued the coal while getting rid of gunk and impurities. Steel mills, which needed high, even, and longer-lasting burns for steel production, required coke.
For coal companies, mining and processing of "coal and coke" increased revenues from all grades of coal. At one point, Fayette County and Washington County both in SW Pennsylvania were dotted with "beehive" coke ovens used to burn off coal's impurities.

What are advantages of coke over coal?
coke burns without producing smoke and leaves no residue... also its calorific value (or the amount of heat it produces) is higher than coal... Coke is the purest form of carbon . It is used in the manufacturing of steel and in the extraction of many metals . coke has least amount of carbon arond 27%
What is the difference between pet-coke and coal-coke?
Pet-coke, or petroleum coke, is a byproduct of the oil refining process, while coal-coke is a byproduct of coal carbonization. Pet-coke has a higher carbon content and lower impurities compared to coal-coke, making it a more efficient fuel source. Pet-coke is typically used in industrial processes, while coal-coke is mainly used in the steel industry.
What are the characteristics for Anthracite Coal?
Anthracite coal is a type of coal that is hard, shiny, and has a high carbon content (over 87%). It is known for burning cleanly with little smoke or odor, making it a preferred choice for residential heating. Anthracite coal is also the oldest and rarest form of coal, formed over millions of years of intense pressure and heat.
What does bituminous coal?
Bituminous coal is a type of coal known for its high carbon content and energy value. It is widely used in electricity generation, steel production, and industrial processes due to its relatively high heat content compared to other types of coal. Bituminous coal is formed when heat and pressure are applied to organic matter over millions of years.
Difference between Metallurgic coke and petroleum coke?
Pet coke is a carbonaceous solid derived from oil refinery cracking processes. Marketable coke is coke that is relatively pure carbon and can be sold for use as fuel, in the manufacture of dry cells, electrodes, etc. Needle coke, also called acicular coke, is a highly crystalline petroleum coke used in the production of electrodes for the steel and aluminum industries. Catalyst coke is coke that has deposited on the catalysts used in oil refining, such as those in a catalytic cracker. This coke is impure and is only used for fuel. Petroleum coke's high heat and low ash make a good fuel for power generation in coal-fired boilers but is high in sulphur and low in volatile content which pose some environmental and technical problems with its combustion.Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is "coked" or heated in an oxygen-free atmosphere until all volatile components in the coal evapoarate. The remaining material is called "coke", sulphur content is low in this form. Most metallurgical coke is used in iron and steel industry processes such as blast furnaces, sinter plants, and foundries to reduce iron ore to iron. Over 90% of the total metallurgical coke production is dedicated to blast furnace operations.

Where was coal burnt on the Titanic?
Titanic had 159 furnaces burning over 600 tons of coal a day.
In what state can you see the burning coal beds?
The burning coal beds can be seen in the state of Colorado, specifically in the town of Crested Butte. The fires have been burning underground for over a hundred years and can sometimes be visible through fissures in the ground.
What is the black solid that is formed in the combustion of hexane?
Coke, most likely. Coke is the carbonaceous residue left over from the thermal "cracking" of hydrocarbons (the term is also used to describe the residue left over from coal combustion).
What are some of the environmetnal concerns in the northeast of America?
I can mostly speak about the coal regions, both the anthracite (hard coal) and bituminous (softer coal). The anthracite coal region extend from lower western New York State to the north, New Jersey to the east over to central Pennsylvania. The bituminous coal region extends from lower eastern New York State, and from Central Pennsylvania west to Indiana, and to the south from West Virginia to Kentucky.AirWherever there had been large coal mines, there was also heavy coal train usage, and both Coal-Coke furnaces as well as Steel Mills that ran on energy produced from burning coal or coke. (Coke is a product created by burning coal.) Bituminous coal burns "hot", so it was preferred for home heating and burning to give energy to steel factories, as well as to run passenger and freight trains.BUT, burning coal or coke produces dirty smoke. Throughout many towns, the dirt from decades of coal burning can still be seen on (and in) buildings and homes. Air pollution in these States used to be quite heavy. Fog would settle in valleys and hang in the air because the fog mixed with smoke. After steel mills closed, along with legislation against pollution, the air quality has greatly improved. Yet, as long as humans rely on fossil fuels, air pollution remains a high risk.Ground and WaterThroughout these States are old abandoned coal mines and in-use mines. Until the last 30 years, the coal mines expelled tons of contaminated water. Run-off from coal drilling along with methane released from coal mines entered fresh streams and ponds. These fresh water sources feed some water wells through ground water (underground water tables). Therefore, fresh water wells also become contaminated. Also, plants and trees died because of the pollution. Many of these effects from old mines have been corrected, but it will take decades for nature to recover.These are just two areas of environmental concerns particular to northeast and the Mid-Atlantic states. But without coal, many things we take for granted would disappear.

Is coal a inexhaustible resource?
No, coal is not an inexhaustible resource. It is a finite resource that forms over millions of years from the remains of plants and trees. Continued extraction and burning of coal can deplete its reserves and contribute to environmental issues such as air pollution and climate change.
Why are there social and political problems associated with fossil fuels?
The US has one of the richest beds of fossil fuels, namely bituminous coal. The geological region called The Pittsburgh Coal Seam extends through many States, including PA, WVA, OH, IN, ILL, and KY. Bituminous coal is a cheap fuel that burns hot. It was used exclusively in home / business heating (coal furnaces), and coal or coke (made from coal) fueled Mills and Factories. The US also has a seam of anthracite coal, which burns less hot and is less preferred over bituminous coal.However, burning coal is dirty. It produces air pollution that contains numerous chemicals. The coal dust from burning the coal can exist in homes/buildings for a century or longer. Coal dust leads to or aggravates many lung diseases. It is a risk to public health, as well as the health of the planet. Social-health concerns often conflict with political concerns, especially in States and Districts that have a high percent of coal miners. Workers risk losing their jobs if society turns away from coal as fuel.
