If you are wondering i am the hardest existing form of coal with lowest levels of impurities. and i am relatively composed of pure carbon. what am i?
There are several kinds of coal, classified according to their volatile content. There are several types of coal, which are classified according to their volatile content.
Anthracite coal is the hardest coal and has the highest calorific value.
Anthracite is the smallest coal, which makes it a particularly ideal fuel. It is the hardest coal and has the highest calorific value. On the other hand, the pollution caused by its use is worth discussing: this coal releases sulfur, nitrogen oxides and greenhouse gases into the atmosphere.
Most of these are emitted by diesel vehicles, but the emission is also likely to be the cause of climate change. The carbon dioxide gas that is released from coal production is also a critical source of methane, or “good stuff.”
Other greenhouse gases are also released. The CO2 at these temperatures is produced by the burning of coal. The combustion of coal produces methane, or CO2. The greenhouse gas is also released from the burning of diesel cars because it is likely to be a greenhouse gas. So the rate in which carbon dioxide, nitrogen oxides and greenhouse gases are released (and how they are released) are important for us to understand. The Carbon Cycle is the process whereby global temperatures rise rapidly and eventually increase so that there is a carbon cycle . That new global temperature change is caused by a change in the global amount of carbon dioxide.
Anthracite coal : In addition to the low content of volatile substances (as a sign of energy performance), humidity level is the first selection criterion.
