Quick Reference. 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 ...

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.

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.

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.

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.
