The Bergius process is a method for the production of liquid hydrocarbons, such as gasoline, diesel, and jet fuel, for use as synthetic fuel. This method was developed by Friedrich Bergius and patented in 1913. The process involves the hydroliquefication of brown coal, also known as lignite, into crude oil.

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] Process

4. Thermal conversion. The action of heat to break down complex feed materials is found in various processes ranging from pyrolysis to catalytic liquefaction. All of these processes involve thermal cracking of the feed material, which can be biomass, coal or organic waste.

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.

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.

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.

Coal resources have been used to produce liquid transportation fuels by several process routes, collectively referred to as coal liquefaction or, more generally stated, as Coal to Liquids (CTL). Early records of coal conversion to liquid fuel date to 1913 and an extraction process developed by Friedrich Bergius in Germany [ 7 ].

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.

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)
