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
After decades of research, the Bergius process, SRCI, SRCII, costeam process, and Hcoal process have proven to be efficient and costeffective to produce synfuel from direct liquefaction [16]. The main difference between SRCI, SRCII, and Hcoal is the addition of hydrogen and catalysts during the liquefaction phases.
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.
Next to the wood gas technology, Fischer and Tropsch invented a synthesis process of diesellike fuel, which was patented in 1925. Conventional vehicle fuel could be substituted, which ultimately covered 90 % of German consumption at that time 40. Another way to produce fuel from brown coal (lignite) is the Bergius Pier process.
The preparation of liquid fuels from solid coal is known as hydrogenation of coal this gasoline is known as synthetic petrol. Bergius Process Direct method: Input : Powdered coal + Ni Oleate catalyst + Heavy oil are made into paste + H 2. Heating in : 400 450°C. Pressure : 200250atm. Process: Powdered coal is converted into gasoline.

Coaltooil plants were constructed in a number of other countries, but only one plant in South Africa is still producing liquids from coal. Liquid production from coal by the Bergius hydrogenation process involved the reaction of hydrogen with a mixture of coal and oil (made in the process) at high temperatures and pressures.
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.
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 ...

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.

A process for making hydrocarbon mixtures (for fuels) from coal by heating powdered coal mixed with tar and iron(III) oxide catalyst at 450°C under hydrogen at a pressure of about 200 atmospheres. In later developments of the process, the coal was suspended in liquid hydrocarbons and other catalysts were used. The process was developed by Friedrich Bergius during World War I as a source of ...

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
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.
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.
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.
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.
