As shown in Fig., coal from hydrogenation yields phenols, BTXaromatics, olefines and higher nuclei aromatics, premium gasoline and diesel fuel (Jüntgen, 1982a).The first step of coaloil processing is distillation by which light oil, middle oil and heavy oil are produced. The processing of these fractions utilizes techniques well known in mineral oil refining.

The methanol to gasoline process uses a zeolite catalyst to specifically produce a range of hydrocarbons only in the LPG and gasoline size ranges. ... 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. ...

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 hydrogen. 2 Bergius termed the process "coal hydrogenation,"

The major problems he confronted and successfully solved were: (1) providing enough hydrogen gas to convert coal into synthetic petroleum, (2) working at the high pressures required for the conversion, and ( 3 ) regulating the reaction's tem perature.

Under high pressures and temperatures, a slurry of crushed coal and processderived oil directly reacts with hydrogen in direct liquefaction (Yan, 1986). It is based on the Bergiusprocess, in which coal is dissolved under high temperatures and pressure (Klerk, 2014).

Bergius did not investigate the influence of different catalysts on the hydrogenation reaction, and his process was a onestage operation; the hydrogenation of coal and the splitting of the products formed took place in one step. This procedure resulted in a smaller amount of the reaction products splitting into gasolinesize molecules.

In 192529, Bureau scientists studied ways to squeeze oil from shale. In 192830 and 193744, the Bureau had experimented with coal hydrogenation, the fundamental process that Germany's Frederick Bergius had first discovered in 1921. Read more about the origins of the Bergius process.

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.

The coaltooil process also interested Standard Oil of New Jersey . As a result, the StandardIG Company was created in 1929, followed in 1931 by the International Hydrogenation Patents Company, through which patents were pooled, and which included Britain's ICI and Royal DutchShell .

Fuel production from coal using the BergiusPier process became topical again in Germany in the 1970s due to the oil crisis at the time. Hydrogenation of coal is a highpressure process at a pressure of up to 700 bar and 550°C. For the hydrogenation process in the reactor under the operating conditions mentioned, hydrogen is required as a ...
