The use of catalysts to refine the coal oil appeared then to be hopeless since coals contained sulfur, a poison for all then known hydrogenation catalysts. The third input was methanol synthesis ...
Coal hydrogenation or liquefaction is a process that converts different kinds of coal into synthetic petroleum by causing the coal to react with hydrogen gas at high pressure and high temperature. Distilling the petroleum yields its major components.
If coal is heated with hydrogen at high temperature and high pressure, it is converted into gasoline. This process of preparation of liquid fuel from solid coal is called hydrogenation of coal. Two methods are available for hydrogenation of coal. They are Bergius process (direct method): Fischer Tropsch Method (indirect method) Bergius process:
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.
As shown in Fig., coal from hydrogenation yields phenols, BTXaromatics, olefines and higher nuclei aromatics, premium gasoline and diesel fuel (Jüntgen, 1982a).The first step of coaloil processing is distillation by which light oil, middle oil and heavy oil are produced. The processing of these fractions utilizes techniques well known in mineral oil refining.
Friedrich Bergius developed the Bergius process, which received a patent in 1913. Karl Goldschmidt invited Bergius to build an industrial plant at his factory, the Th. Goldschmidt AG (part of Evonik Industries from 2007), in 1914. [15] Production began in 1919. [16] [citation needed]
In the autumn of 1913 Bergius filed the first patent on the highpressurehydrogenation of Bergius carried out the research on coal hydrogenation,like that on heavy oil hydrogenation, in steel autoclaves, rotating and stationary, though these auto claves were of much larger capacity400 liters.
ed into oil. The German chemist, Bergius, attempted conversion of coal into oil by a process of chemical reaction involving the addition of hydrogen under high pressure in the presence of a catalyst.

Bergius did not investigate the influence of different catalysts on the hydrogenation reaction, and his process was a onestage operation; the hydrogenation of coal and the splitting of the products formed took place in one step. This procedure resulted in a smaller amount of the reaction products splitting into gasolinesize molecules.
Now syngas is a mixture of hydrogen and carbon monoxide. Synthetic petrol is mainly obtained from a process called Bergius process. In the Bergius process, hydrogen gas and coal are heated together which produces a mixture of hydrocarbons through the process of hydrogenation. The general reaction involved in this process is,

Albania, and These crude oil resources remained on track to provide million tons of finished fuel products in 1944. In addition to the limited refined products based on crude oil, Germany in 1944 was producing liquid refined fuel from coal, using the Bergius hydrogenation process and the FischerTropsch synthe
based on the "Bergius process" began at the KWI. Together with chemist Hans Tropsch, Fischer developed a new way of liquefying coal. Pressure, temperature, and the catalysts used were systematically varied in numerous tests. In indirect hydrogenation, coal and hydrogen are first converted into a synthesis gas by strong heating.
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.
iron catalyst for this process was poisoned by even traces of sulfur compounds. Thus it became generally believed that sulfur poisons hydrogenation cata lysts. Historic Outline of the BergiusPier Process Germany is rich in coal but has only very small petroleum resources. This made conversion of coal into petroleum products of interest.
The success of the first experiments with the highpressure hydrogenation of oil and coal in the years 1912 and 1913 was due to the fact that the laboratory which I directed at that time in Hannover had already developed a method which permitted the conduct of a wide range of reactions in relatively easily operated apparatus at pressures up to a...
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
