ABSTRACT Coal is a solid, brittle, more or less distinctly stratified, combustible, carbonaceous rock. It is being rediscovered as a reliable energy source, which, historically provided the resource base for the industrialization of the United States' economy.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

2. Introduction Coal Coal is a nonrenewable, combustible, hard, black solid substance, consisting chiefly of carbonised plant matter, found mainly in underground seams and used as fuel. Petroleum Petroleum is a nonrenewable, combustible fuel which mainly consists of hydrocarbons, and is generally found in liquid state under the sea beds.

Coal Formation • Unlike oil and natural gas, coal formed from decaying plants in ancient swamps. • When the peat is exposed to high temperatures and pressures, it forms coal. • There are three main types of coal: anthracite, bituminous, and lignite. Anthracite • It is the oldest and hardest form of coal.

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

4. Coal Liquefaction Coal liquefaction is the conversion of coal into a synthetic oil in order to supplement natural sources of petroleum. It is an attractive technology because 1) It is well developed and thus could be implemented fairly rapidly and 2) There are relatively large quantities of coal reserves. 5.

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]
