Coal resources have been used to produce liquid transportation fuels by several process routes, collectively referred to as coal liquefaction or, more generally stated, as Coal to Liquids (CTL). Early records of coal conversion to liquid fuel date to 1913 and an extraction process developed by Friedrich Bergius in Germany [ 7 ].

Even though the process is currently not in use, it has contributed immensely to the development of catalytic coal liquefaction technology.
WhatsApp: +86 18838072829Of the several processes the Germans used to convert coal into petroleum, highpressure coal hydrogenation was the most highly advanced. Its history falls into two broad periods:, during which time its inventor, Friedrich Bergius () developed the process through the first stages of industrialization,

In this way, heavy oil and middle oil fractions are also reused in this process. The most recent evolution of Bergius' work is the 2stage hydroliquefaction plant at Wilsonville AL which operated during 198185.

WhatsApp: +86 18838072829By contrast, other variants of the Bergius process require the use of 15 pounds or more of hydrogen per barrel, resulting in an inherent materials cost. Second, the conventional Bergius process requires high pressure, in the range of 1500 psig to 3000 psig.
WhatsApp: +86 18838072829The 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.
