Friedrich Bergius developed the Bergius process, which received a patent in 1913. Karl Goldschmidt invited Bergius to build an industrial plant at his factory, the Th. Goldschmidt AG (part of Evonik Industries from 2007), in 1914. [15] Production began in 1919. [16] [citation needed]

Bergius Process Major Reference Works Wiley Online Library

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.

Bergius process Alchetron, The Free Social Encyclopedia

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.

by slurrying the ground coal with heavy oil derived from the higher boiling portion of the hydrogenation product. The net oil product was a mixture of petrol and middle oil boiling up to 350 °C. Although Bergius continued to operate his semitechnical plant at Rheinau near Mannheim until 1927, the

PDF Chemical reactions under high pressure

The success of the first experiments with the highpressure hydrogenation of oil and coal in the years 1912 and 1913 was due to the fact that the laboratory which I directed at that time in Hannover had already developed a method which permitted the conduct of a wide range of reactions in relatively easily operated apparatus at pressures up to a...
