The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of highvolatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913. In 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of highpressure chemistry.
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.
The use of nascent hydrogen from hydriodic acid a t 270°C. gave 60% of the weight of the coal as oil. The industrial development of the coalhydrogenation process started with Bergius's work on the constitution of coal, which led to the conclusion t ha t molecular hydrogen reacts with coal a t eIevated temperature and high pressure.
Fuel production from coal using the BergiusPier process became topical again in Germany in the 1970s due to the oil crisis at the time. Hydrogenation of coal is a highpressure process at a pressure of up to 700 bar and 550°C. For the hydrogenation process in the reactor under the operating conditions mentioned, hydrogen is required as a ...
At peak production, Leuna processed 120,000 tons per year of brown coal tar, 40,000 to 50,000 tons per year of bituminous coal middle oils, and 1,200,000 tons per year of dried brown coal, producing 600,000 tons per year of liquid products (40 percent aviation base gasoline, 20 percent motor gasoline, 40 percent diesel oil).

The Bergius process allowed the conversion of coals, tars, and other solid or liquid carbonaceous substances into highgrade liquid fuels through the combination of large quantities of hydrogen ...
The coaltooil process also interested Standard Oil of New Jersey . As a result, the StandardIG Company was created in 1929, followed in 1931 by the International Hydrogenation Patents Company, through which patents were pooled, and which included Britain's ICI and Royal DutchShell .
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.
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.
The Veba Combi Cracking (VCC) process started from development of direct coal hydrocracking processes. The earliest wideranging studies on application of hydrocracking in coal processing were carried out by German scientists in the s [1, 2].Thus, this process of destructive hydrogenation of coal and heavy oils, designated later as "berginization," was developed by distinguished ...

Under high pressures and temperatures, a slurry of crushed coal and processderived oil directly reacts with hydrogen in direct liquefaction (Yan, 1986). It is based on the Bergiusprocess, in which coal is dissolved under high temperatures and pressure (Klerk, 2014).
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

Friedrich Bergius, "Transformation of coal into oil by means of hydrogen," Industrial and engineering chemistry news edition, 4 (10 Dec 1926), 919; ... According to Arno Fieldner and American engineers the wartime cost of either the FT or the hydrogenation process was 2030c per gallon. Google Scholar
Initially the process was taken up only in England and only during the thirties did Bergius manage to continue these experiments in Germany; his main concern was to rationalize the process and to ensure complete recovery of the hydrochloric acid used by constructing intricate devices.
The Bergius Process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of highvolatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913, in 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of high pressure chemistry. [1]
The first commercially available liquefaction process was the Bergius process, developed in Germany as early as 1911 but brought to commercial scale during World War I. This involves mixing coal in an oil recycled from a previous liquefaction run and then reacting the.. Read More. Other articles where Bergius process is discussed: coal ...
