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.

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 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 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.
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 ...
Hydrogenation of both coal and coal tar produces a wide variety of products, depending on the method of operation. Aviation gasoline, motor gasoline, diesel oil, fuel oil, illuminating oils, and lubricating oils have been made from coal and coal tar. Byproducts include gaseous hydrocarbons, sulfur, phenols, wax, and aromatic hydrocarbons.
The Bergius process for coal conversion to hydrocarbons requires temperatures above 450 °C . Mechanochemical synthesis often avoids the use of solvents; in addition, since the energy input...
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]
Originally invented by Friedrich Bergius in the beginning 20th century and patented in 1913, DCL is a reliable process for producing liquid hydrocarbons by catalytic hydrogenation of coal [2], [3]. In the Bergius Process conversion of coal is carried out in presence of a catalyst at high temperatures and high pressures under hydrogen gas ...
Bergius and Bosch were instrumental in developing the hydrogenation method necessary to convert coal dust and hydrogen directly into gasoline and lubricating oils without isolating
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.
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 beginning of the history of synthetic fuels datesgaso to 1913 when the first process of direct coal liquefaction (DLC) by mean of hydrogenation was patented in Germany by the chemist Friedrich Karl Rudolf Bergius () The basic principle of DLC was the use of coal instead of petroleum/crude oil to obtain liquid hydrocarbons used for fuel or as a base for producing other chemicals.
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
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).
Then, after about two decades also Standard Oil became interested in applying hydrogenation in the refinery context, and interestingly the first patent in this area concerned. the destructive hydrogenation of coal in an adaptation of the Bergius process, but with the proviso that a catalyst may be added if desired,, an oxide 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.
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.
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 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.
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 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...
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
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.
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. From ...
The methanol to gasoline process uses a zeolite catalyst to specifically produce a range of hydrocarbons only in the LPG and gasoline size ranges. ...
