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] Contents

coaltoliquids conversion, provided comp lementary means of producing a range of fuels and chemicals. Each offered advantages and disadvantages. Bergius Direct Liquefaction In the early 20th century, German researcher Friedrich Bergius developed a process to directly liquefy coal under high temperature and pressure (coal begins to
I would recommend Bergius process, coal liquefaction, or synthgas methanation as alternatives to traditional crude oil processing. The biooptions also look great, and most people probably end up using algae or arboretums for their first plastic anyway. That said, the default of oil processing is fine; you still get some natural gas, some ...
The middle oil is hydrogenated in order to get more gasoline and the heavy oil is mixed with the coal again and the process restarts. 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.
The paper traces Bergius's development of highpressure coal hydrogenation from a laboratoryscale process to a small factorysize operation at RheinauMannheim, Germany. Bergius carried out several thousand experiments, requiring the testing of more than 200 different kinds of coal, before bringing his hydrogenation process to a successful ...

According to my calculations it should take 2MJ to make the 8 liquefied coal in the Chemical Plant, and to perform the Bergius Process in the refinery. 8 Coal = 48MJ Solid Fuel = + 25 + 2 * (2 + ) =
The other three reactions indicates the Bergius process or hydrogenation of coal. 9. What is the catalyst used in Bergius process? a) nickel oleate b) phosphoric acid c) zirconium oxide d) aluminum oxide View Answer. Answer: a Explanation: In Bergius process the catalyst used is Nickel oleate. In this process the low ash coal is finely powdered ...
The Bergius process is a simple process for converting brown coal completely into crude oil in the presence of certain catalysts. The brown coal is known as lignite. The initial catalyst for brown coal has been used as molybdenum oxide in low concentration, along with sulfuric acid to partially neutralize the calcium humates in the brown coal.
The Hcoal process, for the production of synthesis crude oil, recorded a 131day test run with 70% of this time at the 220 ton day −1 design ... technical developments in the Federal Republic of Germany have been concerned with the improvement of the wellknown BergiusPier process (Kronig, 1978). The overall coal hydrogenation ...
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 ].
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.
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 mixture with hydrogen under high pressures ranging from 200 to 700 atmospheres.
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
One of the main methods of direct conversion of coal to liquids by hydrogenation process is the Bergius process, developed by Friedrich Bergius in 1913. In this process, dry coal is mixed with heavy oil recycled from the process. A catalyst is typically added to the mixture.
The industrial growth of the BergiusBosch coal hydrogenation process in Germany was so successful that throughout World War II when the industry achieved its peak production, the German military's liquid fuel came almost entirely from coalderived petroleum. FRIEDRICH BERGIUS: BACKGROUND TO HIGHPRESSURE COAL HYDROGENATION Friedrich Bergius ...
In the present paper, a brief description of the Bergius process for coal liquefaction and its application to petroleum based products is proposed. The role of catalysts will be examined in the light of expected functions and underlying mechanisms. Criteria for selecting potential active phases will be proposed.

Bergius process. [ ′ber·gē·əs ′präs·əs] (chemical engineering) Treatment of carbonaceous matter, such as coal or cellulosic materials, with hydrogen at elevated pressures and temperatures in the presence of a catalyst, to form an oil similar to crude petroleum. Also known as coal hydrogenation.
Bergius Process The coal is finely ground and dried in a stream of hot gas. The dry product is mixed with heavy oil recycled from the process along with the catalyst like tungsten or molybdenum sulfides, tin or nickel oleate. The mixture is pumped into a reactor. The reaction occurs at between 400 to 500 °C and 20 to 70 MPa hydrogen pressure.
This includes investigations into the reactions of superheated water, its influence on coal and iron and the saponification of organic chlorides, such as chlorobenzene and ethyl ene chloride with aqueous solutions of caustic alkali.
Coal contains about % of hydrogen compared to about 18% of in petroleum. So, coal is a hydrogen deficient compound. If coal is heated with hydrogen to high temperature under high pressure, it is converted to gasoline. There are two methods available for the hydrogenation of coal. Bergius process (or direct method)
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.
Based on a series of documents and longterm industrial investigation, 6 the baseline procedure is a lowtemperature FT synthesis process that uses a 2000 t/d Texaco coal water slurry gasification process, a 100,000 m 3 /h air separation plant, a precipitation iron catalyst, and a M/a slurry bed FT reactor. The main products produced ...
c. Bergius System Developed by Germany to produce aviation fuel and diesel oil during World War II, the Bergius process was one of the forerunners in coal liquefaction technology and has led to the recent development in the United States of the H Coal and Synthoil processes. The Bergius process is the ERDA "disposable catalyst" process.
By 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.
In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w). With the ...
