What is the difference between coal and carbon? Coal or coal

Carbon is the name given to a chemical element and is one of the chemical constituents that make up many substances. It can constitute coal, carbon, activated carbon, coke, graphite, diamond and other different substances whose main components are carbon elements, carbon dioxide gas contains carbon, and a large class of organic compounds that mostly contain carbon elements. Therefore, coal is a specific and personalized name for a substance; Carbon is the name given to a large group of different substances that contain the same chemical element.

There is no difference between the carbon that makes up coal and the carbon that makes up diamond, and when the above large number of carbon-containing substances are decomposed at the atomic level, there is no difference in the carbon atoms contained in each.

Coal has a certain luster, contains a certain amount of mineral oil, etc., and is a relatively tight crystal structure. After the coal is baked in the coke oven, the coal tar and other materials are removed to become charcoal with a relatively loose structure and many voids, most of which are carbon elements. The charcoal made from coal is also called coke.

In addition, there is charcoal made from burning wood, which is called charcoal. Both coal and charcoal can be used as fuel, and most of the coal burns with smoke and possibly some odor. Charcoal burns generally without much smoke and with less odor.

The pore structure of carbon makes carbon have good adsorption, so carbon is often used as an adsorption material for adsorption of moisture, odor, etc.

Coal is mainly a natural component of ancient plants that evolved over tens of thousands of years Carbon is a non-metallic element located in group iva, the second period of the periodic table. Latin for carbonium, meaning "coal, charcoal". The Chinese character "carbon" is composed of the word "charcoal" of charcoal and the stone character of solid non-metallic elements, which is derived from the sound of the word "charcoal".

Its chemical symbol is C, its atomic number is 6, and its electronic configuration is [He]2S22P2. Carbon is a very common element that is widely found in the atmosphere and crust in many forms. Carbon has long been recognized and utilized, and a series of carbon compounds, organic matter, are the foundation of life.

I'm guessing you're asking about charcoal, which is a black fuel that isolates wood from the air and burns it at high heat.

I think it's the same thing, right? It's just that the people in the village call coal carbon?

Trouble, thanks!

Halo: Simple! Coal contains carbon

Coal is coal, charcoal is charcoal, theyNot the same thing

Coal, also known as coal. is a sedimentary rock fromUndergrounddeveloped; CharcoalYes is throughTimberIsolate from the air, add stuffy and close the heat at high temperaturesBurn it outa substance.

Differences between coal and charcoal:

1. The essence is differentCoal is a combustible sedimentary rock. There are two types of charcoal: charcoal and coke.

It is a dark brown or black porous solid fuel left over from incomplete combustion of wood or wood raw materials or pyrolysis under the condition of insulating air.

2. Different ways of formation:Coal is the product of physical and chemical changes such as high temperature and metamorphism that animals and plants in ancient times were buried in the ground for a long time. Charcoal is a black solid made by burning a material in isolation from the air.

3. Different characteristics:Coal has a certain luster, contains mineral oil, etc., and is a crystal with a relatively compact structure. Carbon maintains the original structure of wood, has a developed pore structure and strong adsorption capacity, and is a commonly used adsorbent and catalyst carrier.

4. Different uses: coal is a raw material, and charcoal is a fuel.

Coal is mainly composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, and the sum of carbon, hydrogen and oxygen accounts for more than 95% of organic matter, which is a very important energy sourceAn important raw material for metallurgical and chemical industriesThere are several kinds of sail cover search classifications: lignite, bituminous coal, anthracite, and semi-anthracite. Many people think that coal gas is made from coal, but the fact is that coal gas is refined from naphtha and then refined from the state. Coal can also be vaporized directly to produce water gas (a mixture of carbon monoxide and hydrogen), which can be used directly as a clean fuel.

Charcoal is a kindFuelName. Charcoal is used to smelt iron ore, and even though the chemical composition of charcoal and pig iron smelted from coal is the same, its structure and mechanical properties are still different. The pig iron smelted by charcoal generally has the characteristics of fine-grained structure, tight casting, no cracks, and the pig iron produced with charcoal contains few impurities, which is suitable for the production of high-quality steel.

Because charcoal is reducible, it can be used to reduce ore smelting metals in the metallurgical industry.

Many people mistake coal and charcoal for the same thing because of the word "coal", but they are not.

The difference between coal and charcoal is mainly in the way it is produced, coal is a fossil fuel buried in the groundis naturally formed. And charcoal is to cut down treesWoodenbamboo, etcIt is then artificially fired.

The specific formation process of coal and charcoal:

OneCoal is a rock transformed from animals and plants in ancient times, and its formation method is mainly the product of various physical and chemical reactions in the process of crustal movement. Coal is a kind of combustible sedimentary rock formed after various physical and chemical changes such as high temperature and metamorphism, which is an important part of the earth's crust. In short, charcoal is a naturally formed fuel from the remains of ancient plants.

IICharcoal, on the other hand, is a fuel made from wood that is processed manually. Charcoal is a dark early brown or black porous solid fuel left over from incomplete combustion or pyrolysis of wood raw materials under the condition of isolated air, and its quality can be artificially controlled by conditions such as temperature, time and oxygen.

There are various types of charcoal, ranging from charcoal made from anaerobic firing of trees to coal made from coal mines. For example, the commonly used coke is made by sintering coal in a high-temperature oxygen-free environment, which is mainly used in the field of iron and steel smelting. Charcoal can also be turned into activated carbon after processing; Coke is a combustible substance made by a series of processing at a high temperature of nearly 1,000 degrees Celsius under oxygen-free conditions.

Although coal and charcoal are different things, they have a lot in common in the process of use. For example, charcoal for barbecue includes charcoal and special coal, which are very useful, and coal and charcoal can be burned to make activated carbon, which is a good adsorbent for filtration.

First of all, they are not, they are the same kind of objects, they all belong to the same class.

We all know that China has a lot of coal celery ore used to generate electricity, boil water for cooking, charcoal is artificial, on the basis of coal or other plant stems, artificially processed out of Zheng Xi, such as we often say anthracite, heat and calorific value are relatively high burn-resistant.

For example, the charcoal we often use for barbecues. His shouting changed to the fact that the heat value is released more slowly and more stable, which is suitable for barbecue. We can never use coals for a barbecue.

Trees are buried in the ground for a long time and cannot be decomposed by microorganisms to form coal, which is the organic matter formed after the trees are burned.

Coal is correct. Coal is a solid flammable mineral that was gradually formed by ancient plants buried in the ground and undergoing complex biochemical and physicochemical changes. Coal is the most abundant and widely distributed fossil fuel on the planet.

The main elements that make up the organic matter of coal are carbon, hydrogen, oxygen, nitrogen and sulfur, in addition, there are very small amounts of phosphorus, fluorine, chlorine and arsenic.

Introduction: Coal is known as black gold, industrial food, it is one of the main energy sources used in the human world since the eighteenth century, since the beginning of the twenty-first century, although the value of coal is not as good as before, but after all, for a long time coal is still one of the indispensable energy of our human production and life, coal is also related to the stability of China's industry and even the development of all aspects of society, and the safety of coal is also the most important part of China's energy security. China was the first country in the world to use coal.

In the Xinle ancient cultural sites in Liaoning Province, coal handicrafts were found, and Gongyi City, Henan Province also found the ruins of using briquettes to make iron in the Western Han Dynasty.

1. The essence is different: coal is a kind of combustible sedimentary rock formed after various physical and chemical changes such as high temperature and metamorphism, which is an important part of the earth's crust, and charcoal can be divided into charcoal and coke.

2. Different ways of formation: coal is a rock transformed by animals and plants in ancient times, and its formation method is mainly the product of various physical and chemical reactions in the process of crustal movement, charcoal is a substance with multiple pores, which can be turned into activated carbon after processing, and coke is a combustible substance made by a series of processing at a high temperature of nearly 1,000 degrees under oxygen-free conditions.

3. Different characteristics: coal has a certain luster, contains a certain amount of mineral oil, etc., and is a relatively tight crystal structure. Coal is baked in a coke oven, and after removing coal tar, it becomes a carbon with a relatively loose structure and a lot of voids, most of which are carbon elements, and the void structure of carbon makes carbon have good adsorption, so carbon is often used as an adsorption material for adsorbing moisture, odor, etc.
