coal purification process

Coalgasification is theprocessof producing syngas-a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4) , and water vapour (H 2 O)-fromcoaland water, air and/or oxygen.. Historically,coalwas gasified to producecoalgas, also known as "town gas".Coal gas is combustible and was used for municipal lighting, and heating ...

Coalwas made out of the ancient plants, 300 million years ago, even before dinosaurs, when huge plants started sedimentation in swamps. In millions of years that followed, mud was frothed over remains, transforming in thatprocesshuge heat in to a pressure, and all these factors combined gave ideal conditions forcoal's"birthing place".

What Is Activated Charcoal and How Does it Work?

Activated charcoal is carbon that has been treated with oxygen.The treatment results in highly porous charcoal. These tiny holes give the charcoal a surface area of 300-2,000 m 2 /g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. The carbon adsorbs a wide range of impurities and contaminants, including chlorine, odors, and pigments.
