WebIt is formed due to the high pressure and high temperature for a long period of time. It is hard, lustrous and has the highest percentage of carbon among peat, lignite, bituminous and anthracite. This is also called as hard coal. Petroleum and natural gas deposits are usually found in the coastal regions. Uses of Coal WebIt is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in low-lying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.

Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker … WebThus Flexicoking is an integrated coking and gasification process for upgrading heavy feedstocks. This process converts these feeds to a 99% yield of fuel gas, naphtha, middle distillates, heavy gas oil, and a low-sulfur coke gas. The remaining 1% is petroleum coke containing metals and other ash components present in the feed.
