High temperature lignite coke
High-temperature lignite coke (BHT coke) is a fuel with a high carbon content , which is produced from lignite through the action of heat under the exclusion of oxygen ( pyrolysis ).
history
Since East German industry urgently needed coke after the Second World War and most of the hard coal traditionally used for its production was stored in western Germany, the two process engineers Erich Rammler and Georg Bilkenroth began researching and developing smelting high-temperature lignite coke in 1949 . This can be used for iron production, in non-ferrous metallurgy and for carbide production.
The two scientists from the Bergakademie Freiberg concentrated their research on the Niederlausitz lignite and were finally able to apply for a patent for high- temperature lignite gasification in 1952 .
The coke was made in both shapeless pieces and briquette forms.
Equipment for manufacturing
The lignite high-temperature coke was produced from 1952 in the large coking plant VEB Braunkohleveredelung Lauchhammer ( Lauchhammer ) and later also in the coking plant in the VEB Gaskombinat Schwarze Pump ( Black Pump ). By-products of lignite coking are tar, medium oil and light oil as well as high-quality gas.
Anniversary celebration after 50 years
For June 14, 2002, former employees and cooperation experts were invited to Lauchhammer on the occasion of the 50th anniversary of the first coke tapping, about which the "Zeitschrift der Lausitzer und Mitteldeutsche Bergbau-Verwaltungsgesellschaft mbH" in their magazine LBMV specifically 4/2002, p. 7 reported.
