· Certain coals can be used to produce chemicals and specialty products. This is a small percentage of the overall coal market. Chemical and specialty coals must meet very specific requirements for the product or chemical process in which they will be used. Requirements (and relative grade terms) may be related to ash and sulfur contents, as with steam coals and metallurgicalgrade coals.
Coal chemicals. For about 100 years, chemicals obtained as byproducts in the primary processing of coal to metallurgical coke have been the main source of aromatic compounds used as intermediates in the synthesis of dyes, drugs, antiseptics, and solvents.

· Coal helped create the carbonbased branch of chemistry we call "organic chemistry.". When coal is heated in the absence of air, its complex mixture breaks down into simpler forms. These ...
· When coal burns, the chemical bonds holding its carbon atoms in place are broken, releasing energy. However, other chemical reactions also occur, many of which carry toxic airborne pollutants and heavy metals into the environment. This air pollution includes: Mercury: Coal plants are responsible for 42 percent of US mercury emissions, a toxic heavy metal that can damage the .
Chemistry of Coal Gasifiion Coal gasifiion involves two distinct stages, devolatilization followed by char gasifiion. Devolatilization occurs quite rapidly as the coal is heated above 400°C. During this period, the coal structure is altered, producing solid char, tars, condensable liquids, and light gases. The distributions of devolatilization product under various heating ...
Currently, conversion of coal into alternative fuel and nonfuel valuable products is in demand and growing interest. In the present study, humic acid was extracted from two different ranks of coal,, low rank and high rank (lignite and bituminous), through chemical pretreatment by nitric acid. Samples of lignite and bituminous coal were subjected to nitric acid oxidation followed by ...

Coaltoliquid (CTL) plants convert coal into synthetic fuels or other chemicals. CoaltoSubstitute Natural Gas (CTSNG) plants gasify coal and produce methane. Both processes use coal gasifiion technologies to gasify with the aid of oxygen to produce syngas, which it then transforms into fuels or other chemicals, using technologies like Fischer Tropsch. These plants are high emitters of CO ...
Coal, a naturally occurring combustible solid, is one of the world's most important and abundant energy sources. From its introduction 4,000 years ago as a fuel for heating and cooking, to its nineteenth and twentiethcentury use in generating electricity and as a chemical feedstock, coal, along with oil and natural gas, has remained an important source of energy.
