In 1913 Friedrich Bergius developed a method for transforming a solid form of coal—lignite—into liquefied oil. The method entails exposing the coal to hydrogen gas under high pressure to form hydrocarbons. The process has been used primarily to produce fuel for vehicles.
4. Thermal conversion. The action of heat to break down complex feed materials is found in various processes ranging from pyrolysis to catalytic liquefaction. All of these processes involve thermal cracking of the feed material, which can be biomass, coal or organic waste.
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

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 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 ...
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.
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,

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.

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 + ) =
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 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.

In the process of coal mining, prevention and control of water hazard is essential. It is the precondition for water hazard control to detect and determine the distribution of underground waterconducting channels. In urban environments, traditional methods such as active source seismic exploration and transient electromagnetic exploration commonly used in the field are difficult to carry out ...
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 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 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 co...
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.
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 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.

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)

The paste is pumped along with hydrogen gas into the converter, where the synthetic paste is heated to 400 450°C under a pressure of 200 250 atm.
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 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.

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.
