Anthracite

Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism. Anthracite is shiny black, hard and brittle (see Figure 2.8) and has the highest fixed-carbon content (approximately 86–98%).Due to its low volatile matter (2–12%), anthracite''s combustion process is slow. Most anthracites have low-moisture content (about 3–6%) and their ...

Anthracite | Tradeasia International

Anthracite coal, commonly known as hard coal or mineral coal with a bright, sub-metallic, iron-black luster, consists of nearly pure carbon and burning almost without flame. Anthracite represents the highest rank of coal, was formed in the coalification process when fossil sedimentation was subject to high pressures over millions of years.

Petroleum and Coal

Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster. It contains between 86% and 98% ...

Bituminous coal contains about 78-86% carbon, whereas anthracite contains about 94-98% carbon. Bituminous coal also contains volatile matter and moisture in proportions higher than those in anthracite coal. Moreover, when pure anthracite coal is burnt, smoke or smell is not produced. Hence, the use of anthracite coal is more than that of ...

Anthracite coal generally has the highest heating value per ton on a mineral-matter-free basis. It is often subdivided into semi-anthracite, anthracite, and meta-anthracite on the basis of carbon content. Anthracite is often referred to as "hard coal"; however, this is a layman''s term and has little to do with the hardness of the rock.

Determining the Chemical Analysis of Coal

Every sample of coal has been buried and has, therefore, been affected by the coalification process. The process is similar to cooking an egg. Once an egg is heated, it is somewhere between soft boiled (lignite) and burnt (anthracite). Coal is ranked from lowest to highest: lignite, bituminous and anthracite.
