WEBSep 20, 2018 · Explainer: Where fossil fuels come from. The liquid fuels that power most vehicles have been millions of years in the making. One of the most widespread beliefs about fossil fuels — oil, natural gas and coal — is that these substances started out as dinosaurs. There's even an oil company, Sinclair, that uses an Apatosaurus as its icon.
WEBThere are four stages in coal formation: peat, lignite, bituminous and anthracite. The stage depends upon the conditions to which the plant remains are subjected after they were buried – the greater the pressure and heat, the higher the rank of coal.

WEBThe coalifiion of peat to brown coal transforms the degraded plant matter from a hydrosol (an aqueous dispersion containing about 10% solids) to a colloidal gel of about 3040% solids. The water in brown coal is an integral component of the structure and its removal results in the irreversible loss of the gel structure, the formation of a xerogel.
WEBDec 10, 2023 · Stage one in coal production is peat. Peat is a fibrous substance that is oxidized by water and carbon dioxide.
