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.

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.

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)

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.

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 ...

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 ...

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 ...

Coal is a black rock derived from peat that is commonly used as a fuel source. It can exist in lignite, bituminous, and anthracite forms and can be broken down into synthetic fuel through the Bergius process. Additionally, coal is responsible for production of coke, which has industrial applications. Explanation: The material in question is coal.

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.

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.
