WEBJan 23, 2020 · Coal comes in three main types or grades. First, the swampy peat is squeezed and heated to form brown, soft coal called lignite. In the process, the material releases hydrocarbons, which migrate away and eventually become petroleum. With more heat and pressure lignite releases more hydrocarbons and becomes the highergrade .
