One of the main methods of direct conversion of coal to liquids by hydrogenation process is the Bergius process. [1] The Bergius process was developed by Friedrich Bergius in 1913. In this process, dry coal is mixed with heavy oil recycled from the process. Catalyst is typically added to the mixture.
