Chemicals from direct coal liquefaction — Kyushu UniversityCoal and heavy crude can be converted into light liquid hydrocarbons through several routes, such as liquid hydrocarbons produced through pyrolysis, direct hydrogen addition, and gasifiion of CO and H 2. Coal liquefaction produces C1C3 gaseous hydrocarbons, naphtha, and middle distillates (kerosene and gas oil) as petroleum substitutes.
What Is The Chemical Composition Of Bituminous Coal · What Is The Chemical Composition Of Bituminous Coal? Bituminous coal has a composition of about % carbon % hydrogen % oxygen % nitrogen and % sulfur on a weight basis. This implies that chemical processes during coalifiion must remove most of the oxygen and much of the hydrogen leaving carbon a process called carbonization.
