a) Peat: 60% of carbon :: Anthracite:​

Answer 1

Answer:

90 % of carbon is present in anthracite is a hard coal it regarded as the highest grade of coal

Answer 2

Answer:

Peat: 60% of carbon :: Anthracite:​ 86% of carbon

Explanation:

All types of coal are minerals and rocks primarily composed of carbon. About 25% of the world's primary energy and 40% of the world's electricity are produced by this fossil fuel. But not all of the coal used is the same; It comes in varying amounts of carbon, which determines the coal's quality. Coal of higher quality burns for longer, produces less smoke, and generates more energy than coal of lower quality.

The energy densities and carbon contents of coal are listed in the table below. In addition, the moisture content prior to drying and the volatile content after drying are listed.

Types of Coal

[1] Coal Dry, Carbon content (%) Moisture content before drying (%) Dry, volatile content (%) Heat Content (MJ/kg)

Anthracite 86-92 7-10 3-14 32-33

Bituminous coal 76-86 8-18 14-46 23-33

Sub-Bituminous coal 70-76 18-38 42-53 18-23

Lignite 65-70 35-55 53-63 17-18

Peat 60 75 63 69 15
