In the early 20th century, German researcher Friedrich Bergius developed a process to directly liquefy coal under high temperature and pressure (coal begins to dissolve above 250 degrees centigrade), and then "crack" the coal molecules into smaller molecules using hydrogen. 2 Bergius termed the process "coal hydrogenation,"

Indeed, coal hydrogenation was a neglected reaction until the first decades of the twentieth century, when chemists began to study the hydrogenation process extensively. Two factors contributed to the eventual success of the hydrogenation process: the introduction of metallic catalysts and the application of high pressure. Al

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.
