Lignite is a inferior grade coal due to less cv and carbon content as compare to that of bituminous coal.
One difference is their carbon content: peat and lignite have lower carbon content compared to bituminous and anthracite coal. Another difference is their formation process: peat is not fully coal yet, as it is the earliest stage of coal formation, while anthracite coal is the highest grade and the result of further coalification processes.
The main types of coal are anthracite, bituminous, and lignite. Anthracite is the highest rank of coal and has high carbon content, making it the cleanest burning coal. Bituminous coal has a lower carbon content and is commonly used for electricity generation. Lignite is the lowest rank of coal, with the highest moisture content and lowest carbon content, making it less energy-dense than anthracite and bituminous coal.
The four stages of coal formation are peat, lignite, bituminous, and anthracite. Peat is the earliest stage, and as coal matures through heat and pressure, it progresses into lignite, bituminous, and eventually anthracite, which is the highest grade of coal.
Peat Lignite Bitumen Anthracite
The five steps of coal formation are: Peat formation: Plant material accumulates in wet environments. Lignite formation: Compression and heat turn peat into lignite, a soft coal. Sub-bituminous coal formation: Further compression and heat transform lignite into sub-bituminous coal. Bituminous coal formation: Continued heat and pressure convert sub-bituminous coal into bituminous coal, a higher quality coal. Anthracite coal formation: The highest level of metamorphism forms anthracite coal, a very high-quality and hard coal.

Yes. Lignite is also known as brown coal. It is not exactly the same as coal (bituminous or anthracite) but it is near the beginning of the process that makes coal. Lignite has about 1/3 to 1/2 the carbon content of coal.
Lignite transforms into bituminous coal through the process of coalification, which involves the progressive physical and chemical alteration of the organic material in the peat. With increasing depth and pressure, lignite undergoes a series of changes, including the loss of moisture, gases, and some hydrocarbons, resulting in the formation of bituminous coal.
