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.

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.
