One of the main methods of direct conversion of coal to liquids by hydrogenation process is the Bergius process, developed by Friedrich Bergius in 1913. In this process, dry coal is mixed with heavy oil recycled from the process. A catalyst is typically added to the mixture.

Bergius Process The coal is finely ground and dried in a stream of hot gas. The dry product is mixed with heavy oil recycled from the process along with the catalyst like tungsten or molybdenum sulfides, tin or nickel oleate. The mixture is pumped into a reactor. The reaction occurs at between 400 to 500 °C and 20 to 70 MPa hydrogen pressure.

In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w).

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.

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.

Next to the wood gas technology, Fischer and Tropsch invented a synthesis process of diesellike fuel, which was patented in 1925. Conventional vehicle fuel could be substituted, which ultimately covered 90 % of German consumption at that time 40. Another way to produce fuel from brown coal (lignite) is the Bergius Pier process.
