Developed by NCB at Coal Research Establishment, Stoke Orchard, UK, the process involves extraction by a solvent like toluene above its supercritical temperature and pressure. The extract is separated from the solvent and hydrocracked to produce liquid distillates. It gives an yield of 14% gasoline and 35% diesel.

100th Anniversary: Bergius Process. The Bergius process is a method for the production of liquid hydrocarbons, such as gasoline, diesel, and jet fuel, for use as synthetic fuel. This method was developed by Friedrich Bergius and patented in 1913. The process involves the hydroliquefication of brown coal, also known as lignite, into crude oil.

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
