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).
However, the Bergius process DCL plants were chosen in 1939 when Germany expanded production during World War II, because these were further developed and could be more readily scaled to larger size, eventually processing up to 350 t of coal and yielding 250,000 L of gasoline/day. ... solvent extraction, and direct hydrogenation of coal.

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.
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).

Bergius process The Bergius process (Storch, 1945), like the PottBroche process, is more of historical interest than current commercial interest but it was a process that literally paved the way for the development of catalytic liquefaction of coal. The process involves the conversion of coal (slurried with a heavy oil) in the presence of hydrogen and a catalyst (iron oxide) at 350°F500°F ...

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. The Bergius process was extensively used by Brabag, a cartel firm of Nazi Germany. Plants that used the process were targeted for bombing during the Oil Campaign of ...
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. [1] Process
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
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 .
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.
In 192529, Bureau scientists studied ways to squeeze oil from shale. In 192830 and 193744, the Bureau had experimented with coal hydrogenation, the fundamental process that Germany's Frederick Bergius had first discovered in 1921. Read more about the origins of the Bergius process.
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,
coal liquefaction, any process of turning coal into liquid products resembling crude two procedures that have been most extensively evaluated are carbonization—heating coal in the absence of air—and hydrogenation—causing coal to react with hydrogen at high pressures, usually in the presence of a hydrogenation was extensively used in Germany in World War II to ...
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.
Coal hydrogenation converts different varieties of coal into synthetic petroleum or oil by reacting coal with hydrogen gas at high pressure and high temperature. Bergius was the first to hydrogenate coal successfully and to foresee the commercial development of a synthetic liquid fuel in dustry. He believed that coal hydrogenation provided ...
Engineering Chemistry Questions and Answers Synthetic Gasoline from NonPetroleum Sources 2. This set of Engineering Chemistry Questions Answers for Exams focuses on "Synthetic Gasoline from NonPetroleum Sources 2". 1. Which type of coal is used in Bergius process? a) Anthracite coal. b) Steam coal.
The use of nascent hydrogen from hydriodic acid at 270°C gave 60% of the weight of the coal as oil. A fundamental improvement is achieved by the division of the hydrogenation process into two stages—namely, (1) liquidphase hydrogenation and (2) vaporphase hydrogenation. This twostage process for the hydrogenation of tar proves useful also ...
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.
In the Bergius process, liquid hydrocarbons are produced through hydrogenation of coal dust at high temperature and pressure. In the FT reaction, a mixture of carbon monoxide and hydrogen is converted into liquid hydrocarbon at elevated temperature and normal or elevated pressure in the presence of a catalyst of magnetic iron oxide.
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.
without refining it could not compete with gasoline obtained from natural pe troleum. In scientists and engineers at the Badische Anilin und Soda Fabrik (BASF) plant in Leuna remedied these defects of Bergius's process and undertook the commercial development of highpressure coal hydrogenation in Germany.
However, the Bergius process DCL plants were chosen in 1939 when Germany expanded production during the Second World War, because these were further developed and could be more readily scaled to larger size, eventually processing up to 350 tons of coal and yielding 250,000 L of gasoline per day.

The major problems he confronted and successfully solved were: (1) providing enough hydrogen gas to convert coal into synthetic petroleum, (2) working at the high pressures required for the conversion, and ( 3 ) regulating the reaction's tem perature.

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.
It has coal reserves of million tons of coal and a market cap of million, producing of value for each ton of reserves. Now, consider Sunoco, Inc., it has no oil reserves and ...

Pott Broche extract, but probably converted to Bergius hydrogenation process. Coal supplied from Matthias Stinnes shafts III and IV, about 1 mile to the north. (b) Power Plant: Large power plant with two chimneys. (c) Gas manufacture: Linde separation of H2 from coke oven gas. Plant dimen
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.
