The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of high-volatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in In Bergius was awarded the Nobel Prize in Chemistry for his development of high pressure chemistry.
