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.
