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.
The meaning of BERGIUS PROCESS is a process of hydrogenating usually powdered coal mixed with oil and a catalyst under heat and high pressure in order to obtain chiefly liquid products (such as fuel oil and gasoline).
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...
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.
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. Catalyst is typically added to the mixture. The reaction occurs at between 400 °C (752 °F) to 500 °C (932 °F ...
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 dissolve above 250 degrees centigrade), and then "crack" the coal molecules into smaller molecules using Bergius termed the process "coal ...
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
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.

BergiusIG Hydroliquefaction Process. The Bergius process was operated very successfully in Germany before and during World War II and was a twostage process . Even though the process is currently not in use, it has contributed immensely to the development of catalytic coal liquefaction technology.
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.
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 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 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.

Description: (a) Process: Designed as pilot plant for hydrogenation (700 atms). of 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.
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.

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.
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.

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.

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
Of the several processes the Germans used to convert coal into petroleum, highpressure coal hydrogenation was the most highly advanced. Its history falls into two broad periods:, during which time its inventor, Friedrich Bergius () developed the process through the first stages of industrialization,
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.
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,
