How is coal formed?
Coal is formed from the remains of ancient plants that were buried and subjected to high pressure and heat over millions of years. The process begins with the accumulation of plant material in swamps and marshes, which is then buried by layers of sediment. As the plant material is buried deeper, the heat and pressure cause physical and chemical changes, transforming it into peat, then lignite, and eventually into coal. This process, known as coalification, takes millions of years and results in the formation of different types of coal, such as anthracite, bituminous, and sub-bituminous coal.
-
Can coal be liquefied?
Yes, coal can be liquefied through a process called coal liquefaction. There are two main methods for coal liquefaction: direct liquefaction and indirect liquefaction. Direct liquefaction involves heating coal in the presence of hydrogen and a catalyst to produce liquid hydrocarbons. Indirect liquefaction involves first gasifying the coal to produce syngas, which is then converted into liquid hydrocarbons through a process like Fischer-Tropsch synthesis. Both methods have been developed as a way to produce liquid fuels from coal as an alternative to traditional petroleum-based fuels.

Are peat briquettes as bio-coal better than regular lignite coal fireplace briquettes?
Peat briquettes, also known as bio-coal, are considered better than regular lignite coal fireplace briquettes for several reasons. Peat is a renewable resource, while lignite coal is a non-renewable fossil fuel. Additionally, peat briquettes produce less carbon dioxide when burned compared to lignite coal, making them a more environmentally friendly option. Furthermore, peat briquettes tend to burn more efficiently and produce more heat than lignite coal, making them a more effective choice for heating.
