Bituminous coals are dense black solids, frequently containing bands with a brilliant lustre. The carbon content of these coals ranges from 78 to 91 percent and the water content from 1.5 to 7 percent. Non-coking bituminous coals are used for power generation, cement making and to provide heat and steam in industry.Bituminous coal was produced in at least 16 states in 2021, but five states accounted for about 78% of total bituminous production: West Virginia (30%), Pennsylvania (16%), Illinois (14%), Kentucky (10%), and Indiana (7%). Subbituminous coal typically contains 35%–45% carbon, and it has a lower heating value than bituminous coal.Sub-bituminous coal: Sub-bituminous coal forms from the lignite gel that has been heated to at least 150 0 F. It is harder, blacker, and has a higher heat content than lignite. Wyoming’s coal is sub-bituminous. Major reserves of sub-bituminous coal are also found in Montana, Colorado, New Mexico, Washington, and Alaska.Bituminous Coal: Bituminous coal is typically a banded sedimentary rock. In this photo you can see bright and dull bands of coal material oriented horizontally across the specimen. The bright bands are well-preserved woody material, such as branches or stems.

In the Cooper Basin, coal seams are often interbedded with fluvial sandstones which act as reservoirs for gas and gas liquids. This is the highest ranking coal found in South Australia (bituminous to anthracite) and is similar to many of the Queensland and New South Wales coals.Answer: Bituminous Coal: This coal is most popular because it has 70% to 80% Carbon content and accounts for 98% of the total reserves. ...

Over time, the plants (mostly mosses) and algae were buried and compressedunder the weight of overlying mud and vegetation. As the plant debris sifted deeper under Earth's surface, it encountered increased temperatures and higher pressure.Northeast India has a good deposit of sub-bituminous tertiary coal. The northeast Indian coals have unusual physico-chemical characteristics such as high sulfur, volatile matter and vitrinite content, and low ash content. In addition, many environmental sensitive organic and mineral bound elements such as Fe, Mg, Bi, Al, V, Cu, Cd, Ni, Pb, … ….
