Until today, the process demonstrated the highest oil yields (> 60%) in Coal Liquefaction mode and the highest conversion (>92% of 500+ °C) in Heavy Oil Upgrading mode, by which consequently also the CO2 footprint is minimum. 

The Bergius-Pier process is a proven high pressure hydrogenation process to derive On-spec light hydrocarbons from heavy Feedstocks by thermal cracking and hydrogen saturation in one process unit ("direct hydrogenation“). The main reaction takes place in the Liquid Phase Reactors ("LPH“) in which a bubble column flow regime is established. This ensures maximum backmixing in order to achieve highest conversion of the heavy Feedstocks. Typical reaction parameters are 450 - 490 °C (840 - 910 °F) and 200 - 300 bar (3,000 - 4,500 psi). Further treatment of the LPH products takes place in the integrated Gas Phase Reactors ("GPH“) where the light hydrocarbon products of the LPH get in contact with a fixed bed catalyst to derive On-Spec marketable liquid products. Unconverted products of the LPH are separated prior to the GPH section in the High Pressure Hot Separator and can be utilized in various options, e.g. coking plants.
